Abstract
A retainer bushing for connecting a male member such as a shaft, rod or pin, for example the coupling pin of a motor vehicle clutch pedal, to a mechanical component having a bore accepting the shaft, rod or pin in the bore, for example the input member of an hydraulic master cylinder hydraulically connected to a slave cylinder actuating a clutch release mechanism. The retainer bushing has a flange at one end and one or more longitudinally projecting tangs at the other end. A closure wall is integrally formed at the other end of the retainer bushing. Each tang, which is elastically deflectable outwardly and inwardly, has a radially inwardly directed abutment surface for engagement with the other end of the bore when the flange is engaged at one end thereof, and an inwardly radially directed prong for engagement in a peripheral groove formed in the pin. The bushing is introduced into the bore, with the tangs elastically deflected inwardly, until the tangs snap back to their original position with their abutment surface preventing removal of the bushing from the bore, and the tangs are elastically deflected outwardly when the pin is introduced through the bushing bore until each tang snaps back to its original position with its inwardly directed prong engaged in the pin peripheral groove. The closure wall prevents the pin from being introduced into the bushing through the wrong end.
