ABSTRACT:
A paper binding fastener for use with a conventional prong type fastener includes a rectangular strip of a deformable material which has elongated tab portions at opposite sides thereof. The rectangular strip has a pair of parallel fold lines which allow the rectangular strip member to be folded into a five sided rectangular channel shape. Each of the tab members have a pair of folded lines which are adapted to be folded laterally to form sidewall portions of the five sided rectangular channel. A pair of holes in the top and bottom edges of the rectangular strip member and an additional hole in each of the tab members are in axial alignment at each side of the folded channel member. This allows insertion of a conventional prong type paper fastener. In a modified form, the holes in the tab members are replaced by a plurality of spaced slits to allow a range of adjustment for different paper sizes. In a second embodiment, the paper fastener is formed from two L-shaped members which are secured together by a pair of deformable U-shaped clamps to form a three sided rectangular channel member. Two pairs of axially aligned holes allow insertion of a conventional prong paper fastener.
