ABSTRACT OF THE DISCLOSURE A push-on type fastener (40) is provided for securing a cylindrical member such as a stud shank to an object. Fastener (40) includes generally axially aligned entrance opening (4) and exit aperture (6) surrounded by a resilient hollow projection (2) having a circumferentially continuous side wall. Aperture (6) is a non-circular opening defined between at least two retaining edges of projection (2) that are operative to provide engagement with the cylindrical member enabling the member to slide axially through exit aperture (6) from entrance opening (4) but inhibit movement in the opposite direction and which respectively include warped arcuate sections (3) adjacent the intersection between the respective extremities thereof that are operative to provide a stiffener for the retaining edges for smaller shank diameters and to stretch and prevent the retaining edges from splitting for larger shank diameters.
