What the metal quick-release clasp does
A quick-release clasp is the fastening on a collar that opens and closes without a traditional buckle prong. On the Black Waterproof Biothane Metal Clasp Dog Collar, the clasp is metal, and the collar body is Biothane—a PVC/TPU coated webbing. That combination gives you a waterproof collar that wipes clean and a clasp designed for convenience.
This guide covers how to fasten and release the clasp, how to check that the collar is secure, and how the quick-release design compares with a metal buckle. It sticks to what the product record confirms, so you can make a confident choice.
The clasp and collar at a glance
- Black Waterproof Biothane Metal Clasp Dog Collar: Closure: Metal quick-release clasp fastening. This is the mechanism you'll operate daily, so it's the core of this guide.

Black Waterproof Biothane Metal Clasp Dog Collar - Black Waterproof Biothane Metal Clasp Dog Collar: Material: Biothane (PVC/TPU coated webbing). Explains why the collar is waterproof and easy to wipe down, which affects how you care for the clasp area.
- Black Waterproof Biothane Metal Clasp Dog Collar: Available widths: 20mm and 25mm. Width affects how the clasp sits and how the collar feels on your dog's neck.
- Black Waterproof Biothane Metal Clasp Dog Collar: Free personalised engraving on the clasp (up to 3 lines on 20mm & 25mm widths). Engraving is on the clasp itself, so it's worth knowing before you order.
How to fasten and release the quick-release clasp
- 1. Fit the collar to your dog's neck: With the collar open, place it around your dog's neck so the clasp sits at the side or front, wherever it's easy for you to reach.
- 2. Close the clasp: Bring the two ends of the metal clasp together and push until it clicks or seats closed. The product record describes a quick-release metal clasp, but does not specify a locking mechanism, so check that it feels secure after closing.
- 3. Check the fit: You should be able to slide two fingers under the collar, but not pull it over your dog's head. The record gives neck sizes (Small 23–35cm, Medium 28–43cm), so use those as your sizing guide.
- 4. Release the clasp: To remove the collar, press or lift the release mechanism on the clasp. The record does not describe the exact release action, so familiarize yourself with it before use.
Quick-release clasp vs metal buckle: what to expect
A metal buckle typically uses a prong through a hole, which can be slower to fasten and requires choosing a hole. A quick-release clasp is designed for speed—useful for daily walks, training, or any time you need to put the collar on or take it off quickly.
The tradeoff is that you should check the clasp is fully closed each time. The product record does not confirm a locking safety feature, so treat the closed position as something to verify. If you prefer a traditional fastening, the Black Biothane Buckle Collar is an alternative in the same material.
Choosing the right size and width
- Small (23–35cm neck): Available in 20mm or 25mm width, with Silver, Gold, or Rose Gold hardware. The 20mm width is the narrower option; the 25mm gives more surface area.
- Medium (28–43cm neck): Also available in 20mm or 25mm width and three hardware colours. Measure your dog's neck and pick the size that covers that measurement.
- Width choice: The record lists 20mm and 25mm widths but does not state a recommended dog size for each. Use your dog's neck measurement as the primary guide and choose the width that suits your preference.
Keeping the clasp and collar clean
The Biothane material is waterproof and stink-proof—mud, rain, and river water rinse straight off. The record also notes the collar is quick to clean: wipe down in seconds, no drying time required. That makes it practical for wet or muddy walks.
The record does not give specific cleaning instructions for the metal clasp itself. As a general care step, wipe the clasp along with the collar and check that it opens and closes smoothly. Avoid harsh chemicals unless the manufacturer confirms they are safe.
Safety checks before every walk
Before you head out, confirm the clasp is fully closed and the collar is snug but not tight. The record states the collar has shape-retaining strength—no stretching, even after years of use—which helps maintain fit, but routine checks are still wise.
The product record does not include a break-strength rating or a specific safety certification. If your dog pulls hard or you use the collar for restraint, consider whether a quick-release clasp suits your needs, and consult a trainer if unsure.
