What Is a Plastic Cord End?
A plastic cord end is a fixed terminal accessory fitted to the cut end of a cord, drawstring, lace, string or compatible round elastic. Depending on its construction, it may clamp the terminal section, retain it between two interlocking pieces, conceal it inside a capped body or provide a lightweight colour-coordinated finish.
A plastic cord end is not a movable adjustment mechanism. Use a cord lock or drawstring stopper where the working cord length or gathering needs to be adjusted. Both component types may be used on the same drawstring.
Which Plastic Cord End Should Be Selected?
| Application Requirement | Model to Consider | Specification to Check |
|---|
| Finish a fine string or cord | 3 mm / 0.12 in single-piece clamp-on cord end | Actual cord diameter and retention after closing |
| Finish a thicker lace | 7 mm / 0.28 in clamp-on cord end | Normal and lightly compressed lace diameter |
| Finish the cord inside a decorative cap | 5 mm / 0.20 in or 5.5 mm / 0.22 in bell–pear model | Cord entry and the scale of the outside body |
| Retain the cord between two plastic sections | Clamp-on interlocking cord end | Inner section, outer section and full engagement after closing |
| Minimise terminal-component weight | Plastic cord end | Body weight, fabric thickness and cord construction |
| Coordinate the component with the product colour | Stock-colour or custom-colour model | Available colour, minimum order quantity and approved sample |
E-Buttons Plastic Cord-End Structures
Single-Piece Clamp-On Cord Ends
Single-piece clamp-on cord ends are compact components positioned directly around the terminal section of a cord or lace. The category includes a fine 3 mm / 0.12 in entry and a larger model for laces up to 7 mm / 0.28 in.
The required closing force is as important as the nominal entry. Excess pressure may crack or deform the plastic body, while insufficient pressure may allow the cord to pull out.
Capped Bell and Pear-Shaped Cord Ends
Capped bell–pear models finish the cord inside a wider decorative body. The category includes 5 mm / 0.20 in and 5.5 mm / 0.22 in cord-entry versions.
Check the total body length and outside width in addition to the cord entry. The completed component should remain proportionate to the hoodie, bag, lingerie, sportswear or accessory on which it is used.
Clamp-On Interlocking Cord Ends
Interlocking plastic cord ends hold the cord between two separate plastic sections. The cord is positioned in the inner piece, and the outer piece is fitted over it to close the assembly.
A single “cord-entry” dimension is not sufficient for this construction. The inner opening, outer passage, individual body dimensions and completed closed size must be considered separately.
Interlocking parts do not automatically provide sufficient retention on every cord. Confirm full engagement and pull resistance with the actual production material.
Verified Cord-Entry Groups
| Cord Entry | Product Structure | Compatibility Check |
|---|
| 3 mm / 0.12 in | Fine single-piece clamp-on cord end | Confirm that the cut or heat-sealed terminal section can enter. |
| 5 mm / 0.20 in | Capped bell–pear-shaped cord end | Evaluate the cord diameter and completed body size together. |
| 5.5 mm / 0.22 in | Larger capped bell–pear-shaped model | Check the compressed diameter of soft or filled cord. |
| 7 mm / 0.28 in | Larger single-piece clamp-on cord end | Confirm that a rigid or thick lace does not overload the closure. |
| Model-specific multi-part passages | Small, large and aesthetic interlocking models | Check inner, outer and completed component dimensions separately. |
A nominal cord measurement does not guarantee compatibility. Cords with the same stated diameter may differ in braid density, filler hardness, surface friction and compressibility.
How to Check Plastic Cord-End Compatibility
| Feature to Check | Why It Matters | Application Note |
|---|
| Outside cord diameter | Determines whether the cord can enter the component. | Measure several points with a caliper without flattening the cord. |
| Compressed diameter | Shows how much a soft or filled cord narrows during closing. | Evaluate it together with the normal measurement. |
| Cord surface | Smooth or rigid surfaces may change clamping performance. | Complete a pull test in the actual direction of use. |
| Finished terminal section | Heat sealing, knots or thickened areas may affect insertion. | Plan the assembly sequence before completing the terminal section. |
| Completed outside dimensions | Affect visual scale and passage through other components. | Compare them with cord-lock and eyelet openings. |
| Full engagement | Incomplete closure may allow the pieces or cord to separate. | Confirm that all sections are fully seated. |
Interlocking and Single-Piece Clamp-On Models Compared
| Feature | Interlocking Model | Single-Piece Clamp-On Model |
|---|
| Number of pieces | Uses separate inner and outer sections. | Uses one plastic body. |
| Assembly | The cord is positioned in the inner section and the outer section closes over it. | The body is closed directly around the cord end. |
| Measurements | Inner section, outer section, passage and completed size must be checked. | Entry, body length and closing structure must be checked. |
| Incorrect assembly risk | Incomplete engagement or incorrect cord position | Cracking or cord damage caused by excessive force |
Capped and Clamp-On Plastic Cord Ends Compared
Capped bell–pear models finish the cord inside a wider decorative body. Single-piece clamp-on models provide a smaller and more compact terminal finish.
For a capped model, check the cord entry, body width and total length. For a clamp-on model, check the entry diameter, body length and required closing force.
Plastic and Metal Cord Ends Compared
| Feature | Plastic Cord End | Metal Cord End |
|---|
| Weight | Provides a lighter terminal component. | May create a heavier and more noticeable hardware detail. |
| Appearance | May be coloured, plain, matt, glossy or paintable. | May use plated, painted or decorative metal surfaces. |
| Common structures | Clamp-on, capped and interlocking structures | Crimp-on, bond-on, sew-on, knot-retained and pass-through structures |
| Main selection reason | Low weight, colour coordination and practical assembly | Metal appearance and coordination with other hardware |
For metal alternatives, review the metal cord ends category.
Colour and Custom-Production Options
Depending on the model, plastic cord ends may be offered in black, white, navy, red, yellow, pink, blue and other colours. Some models may be paintable or suitable for custom-colour production.
Not every colour is continuously stocked for every model. Minimum quantity, colour approval, sampling and production conditions must be verified for custom colours, logos or dimensions.

Not every plastic cord end is suitable for every application. Final approval must be based on the verified entry, component structure, colour, minimum quantity and pack information on the individual product page.
Recommended Assembly Sequence
- Measure the normal and lightly compressed cord diameter.
- Thread any required cord lock onto the cord before fitting the terminal component.
- Pass the cord through the garment, bag or footwear channel or eyelet.
- Set the final cord length and terminal allowance.
- Complete the required cutting, heat-sealing or knotting process.
- Position the cord correctly in the entry or inner section.
- Clamp the component, close the cap or fit the outer section over the inner section.
- Confirm full closure and verify that the cord does not pull out.
Incorrect Selection and Assembly Warnings
- A plastic cord end and a cord lock do not perform the same function.
- An opening that is too small may prevent insertion or damage the cord surface.
- An opening that is too large may reduce retention.
- Measure the compressed diameter of soft, filled and elastic cords.
- Check inner and outer component dimensions separately on interlocking models.
- Incomplete engagement may allow the pieces to separate during use.
- Excessive closing force may crack the plastic body or crush the cord.
- A completed cord end may not pass through a cord-lock channel or eyelet.
- Plastic appearance alone does not confirm wash, temperature or outdoor suitability.
- Small-part and detachment risks must be assessed separately for children’s products.
- Complete a sample installation with the actual cord before wholesale ordering or mass production.

Frequently Asked Questions About Plastic Cord Ends
What is a plastic cord end and what does it do?
A plastic cord end is a lightweight fixed terminal accessory used to clamp, cover or neatly finish the cut end of a cord, drawstring, lace, string or compatible elastic.
How do I select the correct plastic cord-end size?
Measure the outside diameter and, for soft material, the lightly compressed diameter. Compare the measurements with the verified entry or internal opening.
How is an interlocking plastic cord end fitted?
The cord is positioned in the inner section and the outer section is fitted over it. Confirm that the pieces are fully engaged and that the cord does not pull out.
How is a capped plastic cord end fitted?
The cord is passed through the model-specific entry or positioned inside the body. The exact closure and retention method must be checked according to the product structure.
Does a single-piece clamp-on cord end require a press?
The required tool depends on the product structure and production quantity. A controlled hand tool may be sufficient, but excessive force can crack the plastic body, so sample testing is required.
Can a plastic cord end be used with round elastic?
It may be used when the entry and clamping structure are compatible. Because elastic changes diameter under compression and tension, test it with the actual material.
Should the cord lock or plastic cord end be installed first?
If the completed cord end is larger than the cord-lock channel, thread the cord lock first and fit the plastic cord end after completing the cord route.
Why do interlocking models have several measurements?
They use separate inner and outer sections. The inner opening, outer passage and completed body size perform different functions and must be evaluated separately.
Are plastic cord ends machine washable?
Wash suitability cannot be determined from the plastic appearance alone. The polymer, colour treatment, assembly structure, wash temperature and detergent conditions must be evaluated.
Can plastic cord ends be produced in custom colours?
Some models may be suitable for custom colours or painting. Minimum quantity, colour approval, sampling and production conditions must be verified for each model.
Is sample testing necessary before wholesale production?
Yes. A sample confirms entry compatibility, complete closure, clamping performance, colour, body size and appearance on the finished product.
