ABSTRACT:
An improvement in a side bar wafer lock, specifically an improvement in the spring retainer of such a lock, and a method of using the spring retainer in the lock are provided. The improved spring retainer of the invention is provided with barbs on the legs thereof such that when the spring retainer is inserted into the slots of the plug of the wafer lock, the barbs bite into the relatively soft metal of the plug to prevent the dislodging of the spring retainer. The method of the invention comprises the steps of forcing the spring retainer into slots in the plug and causing the barbs on the spring retainer to bite into the relatively soft metal of the plug, as opposed to the prior art method of swaging the plug.
