<p>The present invention provides clamp head (10) comprising an arched body (12) having upper and lower faces (28,30), a vertex (26) and opposing unequal length arms (14,16). The body (12) is further provided with a through aperture (36) for a bolt or like threaded fastener which extends between the upper and lower faces (28,30) in the region of the vertex (26). The aperture (36) in the upper face (28) is oval and tapers outwardly through the body (12) in the direction of the lower face (30). The arms comprise a reaction arm (14) having at its distal end (18) a reaction face and a clamping arm (16) having at its distal end (20) a clamping face, the reaction and clamping faces being provided with respective formations (22,24,32,34). The formations (22,24) of the reaction arm (14) extend in a direction which is substantially transverse to the direction of the formations (32,34) of the clamping arm (16).</p> |
