Herm Sprenger ClicLock Fastener Stainless Steel Buckle for Prong Dog Training Collar & Quick Release with Easy Buckle for Medium Large Dogs (3.0/3.2mm)

It makes putting on and off of the collar very easy.

Easy to add to a Herm Sprenger prong collar . No question about quality as Herm Sprenger is top notch dog gear

This buckle works great for putting the prong collar on/off the dog. I can't imagine having to unlock the links, especially on a large, heavy duty collar. We took the protective cover off to make it easier to use. In cold weather, it was extremely hard to use, and the spring lock is so tight really isn't necessary. Even though somewhat expensive, it makes using the collar so much easier and as we walk our dog several times a day, almost a necessity.

Muy recistente, mi perrito se mete seguido al mar con el y sigue en excelente estado, ademas de que es muy facil de usar y da gran seguridad

Was having difficulty taking my dog’s prong collar on/ off but this fastener is a game changer! Very happy with my purchase and would recommend

The clasp was a game changer for my puppy’s pinch collar! So much easier to take on and off. It adds some length to the collar, so I had to remove a link, but I can add it later as he grows. The clasp mechanism is easy to depress and glides easily into the fitting.
