Releasable cable tie

Abstract

A releasable cable tie including a head, a tail, and an elongate strap body therebetween having plurality of teeth thereon. The head includes a passageway for receiving the tail and strap body and a slot formed in one sidewall which is in communication with the passageway, the strap body being insertable into the passageway in a locking direction for forming a loop to receive the objects to be bound. First and second shoulders are integrally attached to the first sidewall on opposite sides of the slot in opposing relation. The shoulders include first and second upwardly extending reinforcing extensions, respectively, which are each spaced a predetermined distance from the first sidewall so as to create an interstice between the extensions and first sidewall. A bridging member extends between the first and second shoulders. The head further includes a latch for releasably retaining the strap body within the head which is pivotally mounted on the bridging member and has at least one locking tooth complementary to each of the plurality of teeth on the strap body. The latch extends into the passageway through the slot such that the locking tooth engages a selected one of the plurality of teeth for substantially preventing movement of the strap body in a release direction. When the cable tie is under load in a locked position, the first and second reinforcing extensions deflect to engage the first sidewall for adding strength to the latch which enables the tie to withstand greater tensile forces. Because the latch is pivotal about the longitudinal axis of said bridging member, it may be pivoted to release the locking tooth from engagement with the selected one of plurality of teeth to permit the strap body to be moved in the release direction, the strap body being easily releasable from the head thereby allowing the tie to be reusable.
