Abstract

L'invention concerne un système d'étanchéité qui comprend un bouchon (21) cylindrique et un joint (22) en forme de cylindre tubulaire, et est installé en deux étapes de montage dans un orifice (23). En position de montage partiel, une dent interne (6) du joint (22) s'accroche à un creux (26) inférieur du bouchon (21). En position de montage final, la dent interne (6) du joint (22) s'encliquette dans un creux (25) supérieur du bouchon (21). La dent interne (6) de la face interne du joint (22) et un moyen de sécurité de la face externe du joint (22) permettent d'augmenter la résistance pour empêcher que le bouchon (21) ne sorte de l'orifice (23). Grâce au système d'étanchéité selon l'invention, la force nécessaire lors de l'installation du système d'étanchéité dans un orifice (23) est réduite tandis que la sécurité du montage et la propriété d'étanchéité du système d'étanchéité sont améliorées.
