1. A method for locking/unlocking a removable module (2) in/from a fixed mounting plate (3) having a support wall (4) for supporting said removable module (2) that has two tenons (5) each provided with a hole (6), the tenons (5) extending out from the removable module (2) to be inserted into openings (7) formed in the fixed mounting plate (3), the method comprising a locking phase, with the steps of:
placing the removable module (2) on the wall (4) of the fixed mounting plate (3), inserting the two tenons (5) into the openings (7) in the support wall (4) of the fixed mounting plate (3);
activating a lever (10) with eccentric cams (11) toward a locked position, the lever (10) rotates between the openings beneath the support wall (4) between an unlocked position and the locked position;
driving, by the rotation, two pins (12) in opposite translational movements, each pin (12) cooperating with the eccentric cams (11) while being secured to an extension (13) that extends transversely to the support wall (4) such that the extension (13) passes through the holes (6) in the tenons (5) of the removable module (2) perpendicularly, and
reversibly blocking the lever (10) in the locked position;
and, in an unlocking phase, in:
unblocking the lever (10) from the locked position;
activating a reverse rotation of the lever (10) until it is in the unlocked position so as to cause the extensions (13) to be withdrawn from the holes (6) via a reverse translation of the pins (12), and
removing the removable module (2) from the fixed mounting plate (3).
