ABSTRACT:
A self-locking cable tie for forming a plurality of wires or the like into a bundle. The tie comprises a stretched elongate flexible strap portion for positioning about the wires. The strap portion is made of a plastic material comprising stretch-oriented molecules. An integral head portion extends from one end of the strap portion and has a strap entrance face, a strap exit face, and a generally transverse aperture extending from the strap entrance face to the strap exit face for receiving the distal end of the strap portion. The aperture has a predetermined strap path therethrough. The tie also includes a locking means non-integral with the head portion and which has a free end portion extending into the strap path and toward the strap exit face. The free end portion and the strap portion each have an engageable component for causing a localized stress concentration in the strap portion. Insertion of the distal end of the strap portion into the aperture from the strap entrance face causes the strap portion to interfere with and to deflect the free end portion to permit tightening of the tie around the wires. The engageable components cause the localized stress concentration in the strap portion upon application of withdrawal forces to enable the free end portion to pierce the strap portion and prevent retrograde movement thereof.
