An elongated chain master link is provided including a removable side link of substantially conventional construction but provided with a transverse opening intermediate the opposite end transverse bores formed therethrough adapted to receive groove master link pin ends therethrough. A retaining clip of elongated panel-like construction is also provided and constructed of spring material such as spring steel. The clip includes opposite end transverse openings formed therethrough and one of the end openings includes communicated large and small width portions while the other opening includes communicated greater and lesser width portions. The small and lesser width portions of the end openings of the clip are spaced apart a distance equal to the spacing between the transverse bores formed through the ends of the side link and the lesser width portion opens toward the opposite end of the link into the greater width portion of the corresponding end opening while the smaller width portion opens transversely of a line extending between the clip openings into the large width portion of that opening. Further, the small and lesser width portion of the clip openings are of a size to snugly receive the grooved end portions of the master link pins therein and the longitudinal center portion of the clip includes a projection seatable in the center opening formed in the side link.
