ABSTRACT:
A one-piece, plastic fastener for lockable engagement in an opening in a panel, comprising a stem having an inner and an outer end. A pair of legs is formed integrally with and extends from the inner end, the legs being in parallelism with one another and in general axial alignment with the stem. Each of the legs has integrally formed therewith at a juncture an elongated arm positioned at an acute angle relative to its leg. The arms each have a free end which terminates in an integrally formed head portion, and the head portions are cooperatively engageable with one another and swingable about the juncture and with their respective arm towards one another to form a complete head having an orifice embracing the stem. The stem and arms are drivable into the opening in the panel to locate the head against an outer side of the panel. Serration means are provided between the head and the stem to maintain the fastener in lockable engagement with the panel.
