ABSTRACT:
A staple-type fastener includes a separate receiving member that is wider than the diameter of the staple prongs. In use, the prongs are inserted through sheets of material to be fastened together and then into the receiving member, which may be fitted with a tab to facilitate removal. One embodiment of the fastener includes a wide upper cross-member to further reduce the tendency of the staple to tear through fastened sheet materials. In another embodiment of the fastener a foldable tab on the receiving member is adapted to have the staple prongs bent over it, the tab facilitating straightening of the prongs for removal of the fastener from the sheets of material.
