Abstract: The present invention is directed to a safety release break-away buckle designed for but not limited to pet collars and large animal halters, to separate at a predetermined magnitude of tension based upon a fraction of the animal's weight or strength, should the animal's collar or halter become entangled on a protrusion as to endanger the animal's health of life, as by strangulation, injury or entrapment. The release is obtained by pulling a lug through a restrictive pair of jaws. The safety release break-away buckle can also be the primary coupling device in a collar or halter.

Abstract: A break-away clip in dog collar allows the dog to break free if the collar is caught on a protrusion or if another dog bites and twists the collar. The break away clip separates into two halves. One half contains two resilient posts and a resilient hook. The posts are separated from the hook by the width of a rod. The second half of the clip contains a rod which is forced between the two resilient posts and the resilient hook. Tension or twisting force on the collar, which is transmitted to the clip, causes the clip to open and free the dog from its collar so the dog can escape.
