An endless belt formed by a connector and a finite length of hollow tubing or solid tubing with recesses at each end. The connector is characterized by a biting edge that has a larger diameter than the inside diameter of the tubing. It is readily flexible away from the direction of insertion of the edge of the tube. The biting edge is formed as a feathered or an erose outlying portion of the base at each of two gripping heads. Once the gripping heads are inserted tension on the tubing causes the feathered edges and adjacent portions of the gripping head to bite into the internal wall of the tubing and form an improved grip therewith.
