Abstract: A connector having dual parallel biting edges at each end of the connector for locking a portion of belting ends into the connector. The height of the biting edges and a centering ring is larger than the transverse dimension of the cylindrical body of the connector and the transverse dimension of recesses at the end portions of an endless belt. The endless belt is formed when the connector is inserted into each end of a finite length of hollow tubing or solid tubing with recesses at each end.

Abstract: 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 one or more biting edges at each end of the connector, each having a larger diameter than the inside diameter of the tubing. Each biting edge is readily flexible away from the direction of insertion of the edge of the tube. The biting edge is formed as a flexible, rough feathered outlying portion of the base at each of the gripping heads. Once the gripping heads are inserted tension on the tubing causes the feathered edges and adjacent portions of each gripping head to bite into the internal wall of the tubing and form an improved grip therewith.

Abstract: 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.
