Round (7) and elongated (7) holes alternate in a row (3) in the first component (2), or the latter can contain a T-section groove. Clamps (6) on the second component (4) form fixing devices, and distance-pieces (8) bear against the edges of the holes or groove in the first one. The clamps can engage behind the edges of the elongated holes or groove, while the distance-pieces can fit part-way inside the round holes or the groove. The first component can consist of a profiled beam, while the holes can be in a pattern comprising one or more round holes and top and bottom elongated holes. |
