Une languette saillante de limitation de position (124) fait saillie à partir d'une paroi externe du fond de la cavité de positionnement (123). Lorsqu'un couvercle de réservoir d'eau (200) est raccordé au raccordement d'étanchéité (10), une structure de raccordement du couvercle de réservoir d'eau (200) est mise en prise à l'intérieur de la cavité de positionnement (123), et la languette saillante de limitation de position (124) vient en butée contre des pièces de véhicule automobile autour du couvercle de réservoir d'eau (200) pour supporter la seconde partie de raccordement (12), ce qui permet d'améliorer la stabilité de raccordement entre le couvercle de réservoir d'eau (200) et le raccordement d'étanchéité (10).
