ASSEMBLY FOR JOINING TWO PARTS OF A MOTOR VEHICLE

The assembly (2) has a fixing element (22) engaged with an elongated hole (24) so as to form a guiding unit that translationally guides bumper skin (4) with respect to a locking element (8) along an axis. The hole has receiving and guiding areas (36) to respectively receive and guide the fixing element to move in translation along the axis relative to a part and the locking element. The areas are separated from each other by a ratchet unit. The skin is sandwiched between the locking element and the part. The locking element moves in translation between locking and unlocking positions.
