Abstract
Abstract An article protecting cable has polygonal inner clamps applied to contiguous portions of the cable inwardly of the looped end portions, said clamps being of a metal sufficiently malleable to permit swaging operations to form detents which project inwardly from all sides of the clamps to bite into and secure the cable extents which pass through the clamps. Covering the inner clamps and secured thereto are similarly shaped polygonal sheaths of a metal relatively harder than that of the clamps to resist cutting or deformation by a thief.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
134 words
The combination with a cable having a doubled-back end portion to form a loop, of a composite clamp applied to contiguous portions of the cable inwardly of the loop, comprising: an inner clamping member of polygonal shape having a pair of adjacent longitudinal bores therein receiving contiguous portions of the cable, walls of said inner clamping member being formed with swaged depressions which provide detents extending toward said bores in a ''''toed'''' relation to engage bore housed portions of the cable; and a metallic sheath conforming to the shape of the inner clamping member and tightly embracing the latter, certain wall portions of the sheath being formed with inwardly displaced detents to enter certain of the swaged depressions in the inner clamping member to prevent removal of the sheath from the inner clamping member.
Claim 2
Dependent Claim
134 words
The combination with a cable having a doubled-back end portion to form a loop, of a composite clamp applied to contiguous portions of the cable inwardly of the loop, comprising: an inner clamping member of polygonal shape having a pair of adjacent longitudinal bores therein receiving contiguous portions of the cable, walls of said inner clamping member being formed with swaged depressions which provide detents extending toward said bores in a ''''toed'''' relation to engage bore housed portions of the cable; and a metallic sheath conforming to the shape of the inner clamping member and tightly embracing the latter, certain wall portions of the sheath being formed with inwardly displaced detents to enter certain of the swaged depressions in the inner clamping member to prevent removal of the sheath from the inner clamping member.
Claim 3
Dependent Claim
26 words
The combination recited in claim 1 wherein the sheath is formed of a metal having a hardness rating greater than that of the inner clamping member.
Claim 4
Dependent Claim
50 words
The combination recited in claim 1 wherein the swaged depressions formed in walls of the inner clamping member extend inwardly from outer surface portions of said member and the detents with which certain wall portions of thee sheath are formed seat tightly in certain of the inner clamping member depressions.
