Want to make your prong collar a quick release, but secure?  Look no further than the new Secure buckle clip prong adapter from Herm Sprenger! 

The awesome stainless steel secure buckle is designed to replace the solid center plate of their 2.25mm and the 3mm/3.2mm prong collars!  Pinch the links together to take out of the stock solid center plate, and pinch again to pop the prongs in the secure buckle.  You will have to adapt sizing, by taking out, or adding links, the secure buckle piece, when fastened, is approximately 2" (from the holes on either side).  Then you have a secure buckle pinch that is easy on and off.
