The unit comprises two triangular elements, each comprising two bent clamping segments (6,7) and a groove for being engaged with the complementary clamping segment (6,7) of the opposite element. Flaps (16) exceeding from a flange at one of the elements are guided through slots (15) in the opposite flange (13) creating a hinge effect in combination with a helical spring, facilitating a temporary joining in order to adjust the parts precisely before the final fixing. |
