ABSTRACT:
A fastener includes a push pin, a plug and an elastic member. The push pin includes a head, a shaft extending from the head, and a clipping foot extending radially from the shaft. Two through receiving holes are defined in the head. A snapping hole is defined in the head and communicates with the receiving holes. The shaft and the clipping foot are between the receiving holes. The plug includes a handle, and two insertion portions extending from the handle. A raised point extends from each of the insertion portions. The insertion portions of the plug can extend through the receiving holes respectively until the raised points are snapped in the snapping hole and the insertion portions extend adjacent to the clipping foot. The elastic member can engage with the push pin to supply an elastic force pointing from the clipping foot to the head to the push pin.
