A connecting link formed of a pair of identical generally C-shaped elongated elements each having an interior pin at a first end and an interior pin-receiving aperture at a second end with the interior of the first end being contoured to mate with the exterior of the second end of another link whereby the elements are first moved transversely of each other to position the second end of each of the elements within the first and second ends of the other of the elements and are thereafter moved longitudinally of each other to engage the pins and apertures to assemble the link.
