Abstract: A device for holding individual sheets contains a circular baseplate with a weight. A U-shaped clip is integrally formed on the upper side of the baseplate and is situated in a plane running obliquely with respect to the upper side of the baseplate. Arranged within the clip is an inner element which forms a gap between its outside and the inside of the clip. Paper can be inserted into this gap.

Abstract: A clip for paper sheets is proposed, which is injection moulded in one piece from plastic. The clip is cross-sectionally U-shaped, the two legs interconnected by a web being flat and their flat sides face one another. In the gap formed in this way between the two legs is placed a clamping leg, which is connected in one piece to the inside of one leg and from there is inclined in the direction of the other leg and in the direction of the web. The paper sheets are slid into the gap, it being possible for the clamping leg to deform, whilst making difficult a drawing out of the sheets.

Abstract: An apparatus for combining a stack of perforated papers contains a pin provided with a widened head, which has a round thread along its shank. The pin is passed through the holes until it abuts with its head. A nut member is screwed onto the threaded shank projecting from the other side. The pin member, together with the nut member, is manufactured by injection moulding and in one piece in a split mould.

Abstract: A folder for receiving documents or the like is formed from a corrugated board or paper blank, which is folded for forming a front sheet and a back sheet. For the retaining of the front and back sheets insert elements are used, which are inserted with pins in the open front faces of the blank. The folder can be produced with much less effort and expenditure than known folders and can be constructed as a hanging folder or as a rubber strip folder.

Abstract: A plastic paper clip having two outer, approximately V-shaped clamping legs connected by transverse webs to a pair of clamping arms disposed within the clamping legs, has a longitudinal slot terminating at an extension element leading to the clamping arms. The extension element is not slotted. When applied to clip paper, the clip is subjected to torque in the area of the longitudinal slot, but the extension element keeps the torque from deforming the clamping arms.

Abstract: A device for the detachable clipping of paper sheets contains an approximately U-shaped clip (11), whose leg ends form longitudinal edges (14), onto which are shaped pins (17). The leg ends of two levers (22) can be snapped into the pins (17) and engages on the lateral faces (18) of clip (11), so as to permit a forcing apart of clip (11).
