<p>The mitred corner connection for section bars having a T-groove includes an angle member whose arms (10') are each detechably clamped into the grooves (5) and a clamping disc (19) which is rotatably mounted in each arm (10') where it can be actuated through the opening (6) of the T-groove (5) of the relevant bar (2, 2'). In the released position the wedge paths (25) of the disc (19) lie open in the T-groove opening (6) but in the clamped position they adjoin either side of the opening (6) inside the T-groove. Where the walls of the grooves are necessarily deformed by the contact of the wedge paths of the disc this occurs inside the angle joint and thus out of sight.</p> |
