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.
