ABSTRACT:
A quick-release paper fastener of polypropylene-ethylene copolymer for stacks of two holed sheets and comprising a tongued base member and a compressor which has resilient hooks provided with transverse V-shaped ribs on the undersurface which co-operates with a central V-shaped groove on the outer surface of the tongue to provide a snap-fit locking and quick release arrangement and the compressor has a transverse bar near each slot which engages with transverse grooves and ribs or notches on the inner surface of the tongue to prevent longitudinal slipping of the tongue when folded over in the fastened position.
