  • (a) a clamp member (1) comprising two identical elements, each element having two semi-circular sectioned portions (6,7) at right angles to one another and the two elements being detachably connected to each other by securing means (2) so that each of the two corresponding semi-circular portions cooperate to form two tubular portions at right angles to each other; and

    (b) a tubular rail member (4) having an external diameter substantially the same as the internal diameter of the tubular portions (6) of the clamp member (1) and adapted to fit in the tubular portion (6) to be clamped therein by the securing means,and further comprising a two-piece generally cylindrical adaptor (13) which is split axially to form two portions (13a, 13b) which are of substantially semi-circular cross-section, each portion having at least two internal webs (14,

         15) of different diameter so that when the adaptor is fitted within the clamp member (1) it can grip the ends of two tubes of different diameters within the clamp member.
