PCT No. PCT/DK93/00409 Sec. 371 Date Jul. 6, 1995 Sec. 102(e) Date Jul. 6, 1995 PCT Filed Dec. 7, 1993 PCT Pub. No. WO94/15759 PCT Pub. Date Jul. 21, 1994A gripping device for use in pressing together two radially protruding ends of a hose clamp constituting a spring wire which is wound into a single loop or coil, the diameter of which can be increased by pressing together the two ends of the spring wire. The gripping device has a rigid jaw with a movable jaw hinged thereto, the jaws having gripping devices for gripping the free ends of the spring wire of the hose champ. The relative movement of the jaws is controlled by a first roller and a second roller, the rollers being seated in a roller head, which is moveable and parallel with an additional roller path of the rigid jaw. During movement, the first roller bears against the additional roller path and the second roller against another roller path as a result of which the friction between the individual parts of the gripping device is reduced to a minimum. In addition, the force of the moveable jaw will increase with a degree of closure without increasing the force applied by a work cylinder to compress the spring.
