The ring mechanism (3) is placed between two side-pieces (6,7) of the folder, these side-pieces preferably being of mutually the same size. In accordance with the invention one side-piece (6) of the folder (1) incorporates a pocket (8) whose mouth (9) is located adjacent that outer edge (10) of the side-piece (6) which is parallel with the ring mechanism (3) or corresponding device.

Abstract: An arrangement for handling documents, papers etc., comprising a so-called ring mechanism (1) for co-operation with hole-punched paper sheets, and a support means such as a folder, calendar (18), binder or file (21; 28) or the like. In accordance with the invention there is attached to the side of the ring mechanism (1) remote from the rings ((3) a first fastener part (8) of a so-called burrfastener arrangement, while a second fastener part (9) of the arrangement is attached to the support means ((15; 21; 28). The fastener parts (8,9) are arranged to co-operate with one another in a manner which enables the ring mechanism (1) to be detachably connected to the support means (15; 21; 28).
