ABSTRACT:
A push-in type fastener for use in a preformed opening in a workpiece. The fastener is formed from plastic and includes a relatively rigid, axially elongated body. An enlarged head is formed at one end and a pair of resilient arms are integrally joined to the body at the other end. The arms are located diametrically opposite one another and extend at an angle toward the head. The free end zones of the arms have catch openings or notches adapted to engage the underside of a panel or workpiece opening when the fastener is inserted therein. In addition, the body includes cylindrical guide sections which lie opposite each other and are displaced 90 degrees radially from the arms. Truncated cone sections are formed above and below the cylindrical guide sections.
