The paper fastener compressor assembly includes a compressor bar having two opposed passages therein for the insertion of the prongs of the compressor base therethrough. A movable cover is hinged to the compressor bar along a common edge, with the cover also sliding axially along the hinge line when closed. The assembly is installed by opening the cover and placing the compressor bar over the extended prongs of the base, and folding the prongs over atop the compressor bar. The cover is then closed over the folded prongs and slid into registry atop the compressor bar to secure the edge of the cover opposite its hinge edge to the compressor bar. A locking tab is provided along the hinge edge of the compressor bar. When the locking tab is crimped, axial movement of the cover is prevented, thus securing the assembly permanently and preventing alteration of the file.
