ABSTRACT:
A retainer apparatus including a retainer clip having a back component, a pair of side plate components, and a pair of front plate components that hold a retractor mechanism for extending and retracting a latch of a lock assembly. The retainer apparatus allows the retractor mechanism to be pre-assembled, ready for connection to a pre-assembled chassis of the lock assembly. One embodiment of the retainer clip is a single formed piece having a back component with at least one post for supporting a spring, side components to provide a bearing surface to slide the retractor mechanism, and front components angled inward to retain the retractor mechanism and the latch. A plurality of prongs extend from the retainer clip to receive the chassis of the lock assembly.
