The fixed part is composed of a single profile with a closed central cell, surrounded by several open cells which can receive windows and fixing and activating means and can be closed, and which contain the safety components and circuits. The movable part comprises a L-shaped profile connected to the fixed part and protecting contacts which cooperate with the components of the fixed part.
