A structural joint suitable for a frame member for furniture, e.g. a leg for a work bench, comprises two tubular members 10, 11 slidable one inside the other. Each member 10, 11 has a longitudinal slot 13 through which a wing nut 16 is passable. The members are secured by engaging a screw 17 in the nut 16 which is so long that it cannot fully rotate inside the inner member 11. Preferably, the slot 13 has enlarged portions 14 which alone can pass a boss of the nut 16. |
