<p>A pair of metal components 2, 3 have first and second pairs of hemi-cylindrical clamp elements 4 and 6 joined by plates 5. At least one of the clamp elements has a dovetail-shaped head 9 which locates in a corresponding notch 8 in the other element. The components are held together by a screw 12 and can be easily assembled to hold a second elongate member 11 alongside a first 10. <IMAGE> <IMAGE></p> |
