Le boîtier (2) présente au moins une surface d'appui (10) s'étendant de façon perpendiculaire par rapport à une direction de montage et servant à l'appui sur le tableau de bord (1) dans la zone de rebord de l'ouverture de montage (4). Le boîtier (2) présente au mois un moyen de fixation (12, 12a) agencé mobile sur la circonférence, lequel moyen de fixation (12, 12a) est agencé mobile sur le boîtier (2) de telle façon par rapport au boîtier (2) qu'il peut être déplacé depuis une position verrouillée vers une position libérée et vice-versa. Le boîtier (2) est serré dans l'ouverture de montage (4) dans la position verrouillée et peut être retiré de l'ouverture de montage (4) dans la position libérée. Le boîtier (2) présente, dans la zone du moyen de fixation (12, 12a), un gradin de boîtier (24) s'étendant dans la direction de montage, lequel gradin de boîtier fait saillie dans le boîtier (2) avec une profondeur perpendiculaire par rapport à la direction de montage et forme une poche.
