Abstract: A clamping device and clamping file for releasably holding sheets of paper or the like is disclosed. The clamping file includes two file covers connected to one another along a folding edge. The clamping device is swivellably fastened to one of the file covers at a window cut-out in the clamping file adjacent the folding edge. The clamping device includes first and second legs connected by a back to form a U-shaped elastic clamp for paper sheets. To facilitate insertion of paper sheets, a longitudinal end area of the clamping device is configured with one of the legs spaced from the other leg to form a paper inserting mouth which is maximally wide at a longitudinal end of one of the legs.

Abstract: A binding folder is provided which includes a foldable plastic cover having a bottom part for anchoring fastening strips which extend through perforations in paper sheets to be held. The top part of the cover forms a counterholder with two pairs of slots for respective ends of the fastening strips. The slots are spaced a predetermined distance from one another and are configured to permit sliding movement of the fastening strips during folding movement of the top and bottom parts so that the paper sheets can be manipulated without requiring removal of same. In certain embodiments the counterholder is provided in a separate folding piece.
