ABSTRACT OF THE DISCLOSURE This invention is directed to a fastening device for the releasable fastening of perforated sheet-like items. It consists of a one-piece moulding comprising a first plate having two legs for insertion through holes in the sheet-like items, and a second plate having holes through which the legs fit. The second plate is detachably coupled to the first plate. When the device is to be used, the second plate is detached and the legs on the first plate are passed through the holes in the items and in the second plate. The legs are then bent through 90° and brought into engagement with a spring-like fastening device on the upper side of the second plate.
