ABSTRACT:
A plastic chain has a link which includes two sections formed of molded thermoplastic material. One end of each link section includes a first opening and is shaped so that when the link sections are joined, the ends will be spaced apart and the first openings aligned. The other end of each section includes a second opening. First and second mating means cooperate to join the other end to form a link. The ends with the first openings are spaced apart a sufficient distance to accommodate at least a portion of the joined other ends of an adjacent similarly-shaped link so that the first openings can be aligned with the second openings in the adjacent link to receive a link pin which is in the form of a hollow tube with a manually releasable resilient latch.
