Fastening arrangement for detachably interconnecting punched documents
Abstract:
The present invention provides improvements in paper fastening to enable a user to remove a desired portion of papers from a fastened stack of papers without having to unnecessarily detach unwanted papers in the stack from the prongs of the fastener. The improved paper fastening arrangement is for use with a fastener having a base including two ends each having a leg extended therefrom, the leg foldable relative to the base. The arrangement comprises a sheath including an extension shaped to slideably engage one of the legs, the extension including an opening that defines a cavity to receive the leg, wherein the extension at least partially covers the leg and is operative to engage through sheet materials. At least one guide tab depends from the extension downward from the opening, the guide tab being foldable.
