摘要：A one piece plastic push-in fastener for insertion into a preformed opening in aworkpiece comprises an axially elongated rigid shank (14) having a head end (12) and afree end (16). A series of flexible wing members (18) extend laterally from the shank (14)to a radial extent greater than the cross-section of the opening. The wing members flex
(18) toward the head (12) to permit push-in installation of the fastener in the opening.However, abutment stops (26) are located between adjacent wing members (18) toprevent their flexure toward the free end (16). Thus, the fastener has low resistance toinstallation and high resistance to removal.
