<p>A device for use in applying tension to elongate members such as wires, comprises an elongate tubular body having a longitudinally tapering passage extending longitudinally therethrough, and two elongate core members adapted to be arranged together and with one or more wires to be tensioned, for wedging reception in the passage in the body. Each core member has a first major surface with a central longitudinally extending semi-circular cross-section groove therein, and a second opposite major surface with a parallel rectangular cross-section groove therein, the major surfaces being joined by opposed minor surfaces to define longitudinally extending corners. The corners defined by the major surface containing the semi-circular groove are concave to receive a wire and the corners defined by the other major surface are convex to mate with longitudinally extending corners of the body when the core members are received in the passage in the body. The core members can be orientated selectively with the first major surfaces of the core members facing each other for entrapment of an elongate member to be tensioned between the semi-circular cross-section grooves of the two core members and the core members can also be orientated selectively with the second major surfaces of the core members facing each other for entrapmont of two or more elongate members to be tensioned respectively between a concave corner of a core member and the body, when the body is pulled in the direction to apply tension to the elongate member or members to be tensioned.</p> |
