ABSTRACT:
A self-locking cable tie for forming a plurality of elongate objects into a bundle. The cable tie comprises an elongate strap including a pair of spaced longitudinally extending side rails joined by a plurality of spaced transverse rungs; and a head extending from adjacent one end of the strap and including a strap entry face, a strap exit face and a strap-receiving aperture extending between the faces. The cable tie further comprises a locking dog including a flexible neck pivotally joining the dog to the head. The dog is formed of a material having greater strength in compressive loading than in shear loading per unit cross-sectional area. Furthermore, the dog extends into the aperture and toward the strap exit face. The dog is sequentially engageable with the rungs and is resiliently biased to extend between adjacent rungs of the strap. The dog further includes a free end portion comprising positioning means for holding the rung to be held. The cable tie further comprises limiting means for limiting pivotal movement of the dog towards the strap entry face after application of strap withdrawal force, so that the major component of the force is directed through the dog from the free end portion to the neck whereby after application of strap withdrawal force, the dog securely holds the strap and the dog is predominantly in columnar loading.
