ABSTRACT:
A one-piece molded thermoplastic cable tie for forming a plurality of elongate objects into a bundle of generally circular cross-section and for compressively holding a pair of objects in engagement. The tie includes an elongate strap including elongate side rails joined by a thin web with the rails and web substantially symmetrical about a first plane intersecting the rails and web and also substantially symmetrical about a second plane normal to the first and intersecting only the web. A plurality of spaced teeth are disposed on one surface of the web.
A locking head joined to the strap includes an abutment wall, strap entry and exit faces, an aperture extending between the faces, and a locking pawl which in its as-molded position, extends into the aperture and toward the abutment wall and strap exit face. The pawl is movable between a threading position wherein the pawl is out of locking engagement with the strap and a locking position wherein the pawl is disposed adjacent the strap entry face and is in locking engagement with the strap. When the pawl is in its locking position, the strap engages the abutment wall and is held between the wall and the pawl whereby attempted retrograde movement of the strap causes the pawl to more firmly engage the strap.
