A unitary element is T-shaped with the crossbar of the T being a head and the upright of the T being a cylindrical collar. A bore passes through the collar and head and may receive a screw therein. A further portion protrudes from an end of the collar remote from the head and has a longitudinally extending planar face which intersects a transversely extending end face of the collar. The further portion longitudinal face and the collar end face engage a longitudinal face and a transverse face of a member, respectively, to fix the element on the member so that it will not rotate relative thereto. A corner member is provided for bracing two structural members which are linked together. |
