The system (1) has two identical connection strips (7, 8) that are interposed by screws (6) between two successive blades (2, 2a) and a corresponding beam (3) that extends perpendicularly. A set of connectors (4, 5) is connected as a single-piece by a median contact zone (a) to form a double connector. The strips are turned with regard to each other by 180 degrees. Each of a set of protruding ends (7a) of one of the connection strips cooperate with protruding ends of another connection strip. The ends are shifted in height with regard to the connectors of one blade. |
