ABSTRACT:
A fastener comprises an anchor and a central pin. The anchor has a top plate to which a central leg is connected. At the free end of the central leg are two anchor arms that extend up and outward from the free end, forming an arrowhead shape. Each anchor arm has an outwardly extending lip connected to its free end. The anchor arms are flexible and can flex inward as the anchor is placed through a hole in an item to be fastened. Connected to the top surface of the top plate is a push pin. Depressing the push pin breaks the connection areas to create a two-piece anchor from the single part. The push pin comprises a push button and a pin connected to the underside of the push button. The pin consists of a vertical post having a channel therein for accommodating the central leg of the anchor. Pushing the push button downward causes the anchor arms to be pushed outward and to anchor the fastener into the items to be fastened.
