Abstract
A quick-connecting link is disclosed having two identical half-links. Each half-link has two arms. One arm ends in a stepwise section and the other arm ends in a stepwise recess. An insert member is held by parallel pins between the two recessed ends of the assembled half-links. The assembly is held together by an expanded sleeve which extends through the insert member, and which lies between and secures the parallel pins.
