ABSTRACT:
There is disclosed a retaining ring for sockets which are attached to the shaft of a power driver, such as the pneumatic air tools, which is a molded elastomer ring with a diametric, integrally molded pin with a metal sleeve surrounding a portion of the pin. The sockets are provided with a receptacle which receives the shaft end of the driver and flats are provided on the shaft and receptacle to transmit torque. A transverse bore is provided in the shaft end and this receives the pin of the retaining ring. The specific improvement of this invention is a metal sleeve about the portion of the pin which extends across a boundry interface between the shaft end of the driver and the inside wall of the socket member to provide reinforcement to the pin, resisting shearing and abrasive wear.
