Abstract
An improvement is disclosed in connector devices such as those comprising connector links for use with chain and cable. Two mating end pieces are provided such as chain half-links, each having a transverse bore therein to receive a connecting pin. The connecting pin has a diameter slightly less than that of the bore in the end pieces so that the end pieces are freely rotatable about the pin and relative to each other. Each end of the pin is chamfered and a split-ring collar is provided for each end of the pin so that once the pin is inserted through the aligned bores in the end pieces, the split-ring collars can be driven onto the respectively opposite ends of the pin to hold the pin in place.
