The push fastener of this invention includes a plastic receptacle held by a metal member to a workpiece, the receptacle having four leaf springs for improved alignment and load carrying ability. Two inclined inner surfaces are provided on the receptacle, one for engagement by the end of the plunger and the other for engagement by the release collar. A lip at the ends of the leaf springs is received within the interior of a washer on the end of the plunger when the fastener is secured, resisting outward displacement of the ends of the leaf springs.
