The fitment has a ramp (113) against which an end (1211) of the arm is supported in a manner that a translation unlocking movement of the locking element causes disengagement of the arm out of a notch (100) in a direction of the arm. The locking element has another arm (122) with an end (1222) connected to an end (1212) of the arm (121) by a bridge (120) for moving the end (1212) in a disengagement direction during the unlocking movement.
