ABSTRACT:
A quick-coupling link to be utilized in conjunction with an identical link has a slot in one of the longitudinal side portions of the link. A tab extends from the opposite longitudinal side portion to adjacent the slot. The tab spans the width of the slot. When a pair of identical links are joined, the tabs prevent the links from accidentally being uncoupled as the slots cannot be brought into disengaging alignment without bending the flexible tab away from the entry to the slot.
