The device (3) has a clamping element (4) comprising arms (5) disposed in a parallel manner, where one arm is mobile in translation along an axis perpendicular to a plane of the arms so as to space or bring closer the arms relative to each other. A locking unit of the clamping element locks the movement of the arms. An intermediate plate formed on a rear side of the clamping element receives a video screen (2) and includes a passage traversed by the locking unit. Two extensions are provided on a free end of the arm opposite to the arm carrying a complementary locking unit. |
