ABSTRACT:
A plastic rivet consisting of rivet body comprised of a flanged head and a leg member extending from the bottom of the head, the rivet body having an axial hole extending through its entire length, and a pin which when inserted into the through-hole, expands the leg member. The leg member of the rivet body is provided with a movable leg which is deflected outward when the pin is inserted into the through-hole of the rivet body so as, for example, to catch and hold a pair of plates through which the rivet body has been passed between the head of the rivet body and the deflected movable leg. Pushing the pin further into the rivet body causes the deflected movable leg to return to its normal position, whereby the fastening action of the rivet is released.
