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 a 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. 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 groove formed in the pin.
