ABSTRACT:
The present fastener for holding a stack of loose leaf pages has a base piece with easily flexible and resilient plastic prongs and a top piece with openings for passing the prongs and sliders for holding the prongs folded down on the top piece. The prongs are constructed and arranged to flex readily when released from beneath the sliders in the top piece and pages in the top of the stack are folded out. The prongs have shoulders near their outer ends for preventing the complete removal of the top piece.
