A set of frame component comprising a plurality of tubes (6) incorporating an internal longitudinal spline member (7) and a plurality of connecting members (9) incorporating two identical spigots (2, 3) ends formed with four longitudinally extending grooves (4) which are spaced about the periphery of each spigot (2, 3) at 90<o> intervals. The spigots (2, 3) of each connecting member are inserted in the ends of the tubes (6) with the splines (7) engaging a groove (4) in the spigots (2, 3) to locate the connecting member at a predetermined desired orientation. |
