Patent attributes
A paper fastener has a base piece with a pair of prongs which may be passed through a pair of keyed slots in a top piece and latched to the top piece to hold stacked papers together. Two latching covers hingedly extend from ends of the top piece. The prongs are folded inwardly against the top piece and the latching covers are folded over the prongs, and the prongs and the latching covers are engaged on a top surface of the top piece. Second teeth on downward facing sides of the folded latching covers engage first teeth on upward facing surfaces of the folded prongs, thereby preventing the prongs from sliding back through the keyed slots. The base piece and the top piece are disconnected by first releasing the latching covers, and then releasing the prongs, so that the top piece can be easily removed to add more pages to a stack of papers or to disassemble the stack of papers.
