Abstract
Abstract The opposite looped ends of an article protecting cable, which can be brought into adjacency for the reception of a lock, have clamps applied thereto which are polygonal with the angles between adjacent sides being obtuse. Bores extending longitudinally through the clamps receive the cable ends which form the loops. By swaging portions of all sides of a clamp, displaced extents of metal form internal protuberances whose ends bite into the bore-inserted extents of the cable ends in inwardly converging, angular relationship and thus very effectively clamp the inserted portions of the cable ends.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
106 words
The combination with a cable having a doubled-back end portion to form a loop, of a clamp applied to contiguous portions of the cable inwardly of the loop, consisting of a polygonal member wherein adjacent walls meet one another in obtuse angles, there being a pair of adjacent longitudinal bores in said member receiving said contiguous portions of the cable, and detents extending inwardly from all of the walls of said member with the detents in one wall being inwardly converging relative to the detents in immediately adjacent walls, said detents biting into and securing the bore-housed extents of the cable and being ''''toed'''' relative thereto.
Claim 2
Dependent Claim
106 words
The combination with a cable having a doubled-back end portion to form a loop, of a clamp applied to contiguous portions of the cable inwardly of the loop, consisting of a polygonal member wherein adjacent walls meet one another in obtuse angles, there being a pair of adjacent longitudinal bores in said member receiving said contiguous portions of the cable, and detents extending inwardly from all of the walls of said member with the detents in one wall being inwardly converging relative to the detents in immediately adjacent walls, said detents biting into and securing the bore-housed extents of the cable and being ''''toed'''' relative thereto.
Claim 3
Dependent Claim
60 words
The combination recited in claim 1 wherein a pair of opposite walls of said polygonal member are relatively wide with the longitudinal margins of one being connected to the longitudinal margins of the other by pairs of connected and angularly related, relatively narrow walls, each detent which extends inwardly from said wide walls engaging both of the bore-housed cable extents.
Claim 4
Dependent Claim
31 words
The combination recited in claim 2, wherein the detents which extend inwardly from said wide walls are relatively elongated, are transverse of said wide walls, and span both bore-housed cable extents.
Claim 5
Dependent Claim
30 words
The combination recited in claim 2 wherein the detents are formed by surface swaging of said walls and said detents tightly engage and deform the bore-housed portions of the cable.
