This anchoring device, in which a maintaining member is disposed between a guiding rail (5) and a device for driving a slidable unit including a tongue, comprises a case (25) having a front side (26) in which is provided a slot (27) through which the tongue projects and of which the edges define two bearing surfaces adapted to cooperate with the tongue so as to withstand tensile forces exerted on the tongue. This device further comprises a device (32) for locking the slidable unit in an active position, adapted to prevent the displacement of the unit in a direction parallel to the guiding and retaining rail (5). This locking device comprises at least one locking element (33, 34) disposed in a cavity (35, 36) provided in the front side (36) of the case, the or each locking element being mounted to be movable between a retracted position, allowing the insertion or the withdrawal of the tongue from the active position, and a locking position in which the active parts of this locking element cooperate with complementary parts of the tongue and with the cavity for retaining the tongue in the active position. |
