An adjustable clamping device for receiving and selectively frictionally engaging an internally disposed inserted member, such as a rope or rod, is disclosed. The clamping device comprises a flexible and readily deformable gripping member of a hollow cylindrical shape, disposed about a generally centrally located first longitudinal axis. The gripping member may comprise a substantially solid sheet of flexible material, or may comprise a mesh material, or may comprise a plurality of flexible strand members. The material for the gripping member may be leather, rubber, synthetic rubber, neoprene, cloth, nylon, rayon, kevlar, or metal, as appropriate. The gripping member is twistably deformable between a straight neutral configuration and a plurality of helically twisted configurations whereat the gripping member reduces in diameter and encloses down onto the inserted member. When the gripping member is twistably deformed from its straight neutral configuration to a helically twisted configuration, it correspondingly reduces in length. First and second handle members in the form of hollow elongate circular cylinders, with the first handle member freely rotatably engaged within the second handle member, are attached one to each end of the gripping member and are biased one away from the other by a coil spring interconnected therebetween, thereby urging the gripping member to a taut condition. In use, the first and second handle members are turned one with respect to the other so as to cause the gripping member to be in a corresponding helically twisted configuration, thus reducing in diameter and thereby frictionally engaging the inserted member.
