A file for holding perforated sheets is provided adjacent its spine with a pair of spaced apart tubular prongs for cooperation with the sheet perforations. The file is provided at its spine with a leaf spring of which a portion protruding from the inner side of the spine, in the position of use of the file, abuts against the web of a substantially U-shaped wire member, the arms of which engage the tubular prongs to retain the sheets to the tubular prongs. The leaf spring portion protruding from the spine to cooperate with the web of the U-shaped wire member has a tongue integral with the protruding leaf spring portion and directed towards the spine of the file. When the protruding leaf spring portion is caused to abut against the web of the U-shaped wire member, the tongue snaps home under the wire to lock the leaf spring to the U-shaped wire member.
A ring mechanism is selectively configurable between an open configuration in which loose leaf pages can be added or removed from the mechanism and a closed configuration in which loose leaf pages are retained by the ring mechanism. Ring mechanism including an elongate frame having first and second frame elements. A hinge pin interconnects the first and second frame elements to permit pivoting movement of the frame elements relative to each other. At least one ring includes a first ring member mounted on the first frame element and a second ring member mounted on the second ring element. At least one hanging member is mounted on the frame for releasably hanging the ring mechanism from a support and inhibiting longitudinal movement of the hanging member relative to the support.
