The fixture comprises a right-angled profile with two identical flanges, each having at least two keyhole type holes. The two keyhole type holes aligned in the same direction are located one after the other in the profile longitudinal direction and with the symmetry axis for the profile slot parallel with the profile longitudinal direction. - The keyhole type hole has its greatest opening at least equal to the head of a pin (10) head inserted in a frame (8) or blade/arch (9). The keyhole type hole slot is less than the head but at least similar to the pin shaft. - (Dwg.2) |
