A safety retainer assembly is disclosed herein for holding a shaped nut in position on a threaded nipple or the like, which includes an annular body having an internal bore configured adjacent one open end to conform with the shape of the nut and having an external shoulder with a stepped opening or hole for receiving the catch of a retaining pin formed in a rectilinear length of a locking clip. Internal splines are provided adjacent the other open end of the body shoulder adapted to receive mating external splines carried on a collar of the nipple to prevent relative movement therebetween whereby the nut cannot back off from its threaded connection with the threaded nipple. The circular locking clip includes a holding ear or dog on one end fitted into the stepped opening at the opposite end thereof from the seating of the release catch that is carried on the other end of the circular safety clip.
