Herm Sprenger ClicLock Fastener Stainless Steel Buckle for Prong Dog Training Collar & Quick Release with Easy Buckle for Small Medium Large Dogs (2.25mm)

Works well with our prong collar. This makes it easy for us to take the color off and on when training.I normally use this in addition to a rolled leather collar so I can take the prong off quickly with a clip when we are not training, which is easy and more comfortable for both me and the dog.I haven't had any problems with it coming unbuckled.It's durable and looks good.

Very secure lock, easy to use. Good that the lock has a sliding cover to secure the button.Take into consideration that adding the lock changed the size of the collar, and there does not seem to be a formula that brings the collar size back to what you started. The collar fit well, adding the lock made it too large (obviously). But taking 1 prong link out was not enough, 2 links out was too much. The difference was not significant enough to take a star away, just be aware.

An absolute MUST Purchase along with the prong collar. There is no way I would be able to squeeze the prongs together to get her collar on and off. Really happy with this - easy on, easy off - makes for an enjoyable experience when we go outside for training.

Easy to install. Fit perfectly. Strong and easy to use. Make sure to insert in the middle of the collar - same number of links on each side- so the collar does not hang off center. Perfect for what we needed and makes it much easier to put the collar on and take it off.

Listen — if you've ever wrestled a prong collar off a squirmy, overly dramatic dog who suddenly acts like you're defusing a bomb around their neck, this thing is a lifesaver. The ClicLock snaps on and off so easy, you'd think it was made by wizards.Bonus: it’s longer than the baseplate, so it bought us some extra slack until those elusive extra links arrive. Downside? The locking part’s plastic, and while it holds up now, I fully expect it to surrender to my dog's Hulk-strength zoomies one day. Still worth it for the sheer sanity it saves.Would buy again, probably in bulk.

Game changer for getting the collar off and on! My mother's arthritis made her unable to use to train her big boy Zeus. With this she is able to fit the collar on easy.

I was hesitant to get this for my 10 month old German Shepherd for fear that the clasp would come undone, but it is very secure and durable. The audible click is also a reassuring sound, and the slide cover protects it from being inadvertently depressed to release accidentally. Very pleased with this addition to her collar, makes putting on & removing much smoother.

Very simple to put on and makes it easy to get collars on and off dog. Great product.
