The device has at least two radially movable jaws (15a, 15b) on the lid (1), a portion (50) for controlling the movement of the jaws (15a, 15b), actuating members (20a, 20b) connected to each of the jaws (15a, 15b) and provided with at least one locking aperture (25a, 25b, 250), and at least one locking valve (10) mounted on the lid (1) and movable into a raised position in which it engages the aperture(s) (25a, 25b, 250) and locks the jaws (15a, 15b). The device is characterized in that it comprises a locking valve (10) combined with two actuating arms (20a, 20b) positionable one above the other at least when the jaws are in the locking position, the actuating arms having respective locking apertures (25a, 25b) arranged to be in register in the locking position.
