The angle piece (10) is used to connect at least two profiled bars, which each have a central hole and a longitudinal groove on one or more external sides. It has perpendicular first (12) and second (14) limbs, which each have a recess for anchoring it to a bar using fasteners. The recess in the first limb is a hole (18), while that in the second limb is an elongated hole (20). Both limbs have at least one supporting wall (16) whose external contour is curved outwards, and which connects together at least sections of the internal sides of the limbs which face towards each other. |
