The connecting system for square profiles (31, 32) with longitudinal grooves comprises a nut (20) which fits into the slot in one profile and a bolt (28) in a longitudinal bore (4) in the other profile which fits into the nut. The bolt is tightened using an Allen key (33) inserted through a slot (35) in the wall of the profile. An independent claim is included for a method for connecting square profiles using the system. |
