Preferably the bore or bores and the reinforcing member or members extend substantially parallel to the axis of the extruded body and their axes lie in a substantially common plane. Alternatively, a single reinforcing member may extend centrally in the extruded body and a plurality of separate bores be arrranged around, preferably helically around, the central reinforcing member.
