ANSTRACT OF THE DISCLOSURE A chain has alternately arranged center links and sidebars that are interconnected by pins of a predeter- mined diameter. An elongated opening is provided in each center link for receiving two pins. Adjacent each end of the elongated opening, lugs project from the center link to restrict the opening opposite the lug, to a transverse dimension less than the pin diameter. Each lug is spaced from an adjacent opening end by a distance enabling one pin to fit between the adjacent opening end and the lug. Each pin has a transverse groove for receiving one of the lugs when the pin is in a predetermined rotational angular relationship with the center link. Thus, the pins can be moved past the lugs, in directions to and from the adja- cent ends of the elongated openings, when the pins are in the predetermined rotational angular relationship for assembly or disassembly of the chain. The lugs prevent collapsing of the chain when the predetermined rotational angular relationship is not maintained. -1a-
