Abstract: A clamp, particularly suitable for tidily restraining a set of sheets, documents and the like, appropriately grouped together in a form suitable for easy consultation thereof, preventing individual sheets from falling out or becoming lost. The clamp includes two clamping jaws longitudinally extending and provided on one side with opposite clamping edges for gripping the set of sheets to be clamped; the two jaws are hinged at one of their ends and are provided with a snap-engaging device which can be manually disengaged to allow the insertion or removal of the sheets. The clamp is particularly suitable for gripping a set of individual paper sheets, magazines, newspapers or for other similar applications.
