A push-in connector provides for easy manufacturing and assembly using a flat-stamped flexible retainer clip. The retainer clip is inserted into the connector and flexes to snap-fit within in the connector. The flex of the clip also flexes wings of the clip which engage with a receiving boss. The flexion of the clip allows for easy push-in of the connector and sufficient resistance to accidental pull-out. The push-in connector design eliminates the need for screw-mounting of the connector. The connector assembly may be manufactured for use in connection with a variety of ball studs, as well as other items such as shafts of various objects and wires, or may be used a fastener.
