Abstract
Abstract A C-shaped wire connecting sleeve is formed having a plurality of elongated ribs pressed into part of its back portion which in turn is joined by two semi-circular end gripping portions. Upon being compressed about an enclosed wire or cable, the ribs not only strengthen the sleeve to resist undesired opening but minimize the inside radius of the enclosing sleeve to further increase the sleeve's compressive gripping force.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
139 words
A wire connecting sleeve having a generally C-shaped configuration comprising: a generally vertical back portion, a pair of curved opposed end portions integral with and extending from said back portion, said end portions being spaced sufficiently to receive a cable therebetween, a plurality of elongated ribs struck from said back portion and parallel to the lateral edges of said back portion, the presence of said ribs leaving correspondingly shaped recesses in said back portion, said ribs being confined to said back portion and terminating short of said curved opposed end portions, said ribs when extending from the outer face of the back portion constituting no more than 30% of the peripheral dimension of the C-shaped configuration, and said ribs when extending inwardly from the inner face of said back portion constituting no more than 25% of said peripheral dimension.
