A device for tensioning and fastening a flexible elongated member, such as a chain or wire. A frame has a pressure bellows and a lever mounted thereon. The pressure bellows is operatively connected to the lever by a shank member whereby the stroke of the pressure bellows is multiplied by the leverage ratio of the lever so that the free end of the lever goes through a increased stroke to tension a flexible elongated member attached to the free end of the lever.
