Abstract
Abstract The invention is concerned with a device for holding a cable suspended from a support, the cable having an aerial support wire connected therealong for supporting same with an end portion thereof securely held by the device. The device of the invention comprises an open-ended tubular member having an inlet end and an outlet end for receiving the cable and support wire therethrough with the end portion of the support wire extending beyond the outlet end and separated from the cable, wire retention means integral with the tubular member for securing the wire end portion to the tubular member and means for connecting the tubular member to the support such that the tubular member lies at a predetermined distance from the support. This device enables an aerial support wire, such as the steel messenger wire of a messenger coaxial cable used in the cable TV industry, to be securely held at the dead-end thereof while preventing the cable from undergoing further separation from the messenger wire when separating forces are exerted thereon.

Claim 3
Independent Claim
274 words
A device for holding a cable suspended from a support, said cable having an aerial support wire connected therealong for supporting same with an end portion thereof securely held by said device, said device comprising an open-ended tubular member having an inlet end and an outlet end for receiving said cable and support wire therethrough with said end portion of said support wire extending beyond said outlet end and separated from said cable, wire retention means integral with said tubular member for securing said wire end portion to said tubular member and means for connecting said tubular member to said support such that said tubular member lies at a predetermined distance from said support, wherein said wire retention means comprise at least one slot formed at said inlet end and having a first portion extending inwardly from said inlet end for receiving said wire end portion and a second portion extending substantially transversely to said first portion for captively retaining said wire end portion received through said first slot portion and into said second slot portion, whereby said end portion of said support wire extending beyond said outlet end is secured to said tubular member by bending said wire end portion adjacent said outlet end so as to extend exteriorly of said member in a direction towards said inlet end, inserting said wire end portion through said first slot portion and then into said second slot portion while applying a pulling force so as to cause said wire end portion to extend closely adjacent said tubular member between the ends thereof and to further bend at said second slot portion for captive retention therein.
Claim 4
Independent Claim
274 words
A device for holding a cable suspended from a support, said cable having an aerial support wire connected therealong for supporting same with an end portion thereof securely held by said device, said device comprising an open-ended tubular member having an inlet end and an outlet end for receiving said cable and support wire therethrough with said end portion of said support wire extending beyond said outlet end and separated from said cable, wire retention means integral with said tubular member for securing said wire end portion to said tubular member and means for connecting said tubular member to said support such that said tubular member lies at a predetermined distance from said support, wherein said wire retention means comprise at least one slot formed at said inlet end and having a first portion extending inwardly from said inlet end for receiving said wire end portion and a second portion extending substantially transversely to said first portion for captively retaining said wire end portion received through said first slot portion and into said second slot portion, whereby said end portion of said support wire extending beyond said outlet end is secured to said tubular member by bending said wire end portion adjacent said outlet end so as to extend exteriorly of said member in a direction towards said inlet end, inserting said wire end portion through said first slot portion and then into said second slot portion while applying a pulling force so as to cause said wire end portion to extend closely adjacent said tubular member between the ends thereof and to further bend at said second slot portion for captive retention therein.
