Abstract

L'invention porte sur un dispositif d'étanchéité extensible (45) comportant: - un bouchon d'étanchéité (47) muni d'un trou de passage de vis (53), - une vis de compression (52) insérée à l'intérieur du trou de passage de vis (53), - une rondelle déformable (58) ayant à l'état non déformé une dimension radiale (D1) inférieure ou égale à une dimension radiale (D2) du bouchon d'étanchéité (47), - une rondelle mobile de compression (59), et - un écrou de vissage (60) destiné à coopérer avec une extrémité filetée de la vis de compression (52), de telle façon qu'une force résultante de serrage (F3) de la vis de compression (52) avec l'écrou de vissage (60) est apte à entraîner un déplacement de la rondelle mobile de compression (59) causant une déformation radiale de la rondelle déformable (58) ayant à l'état déformé une dimension radiale (D1) supérieure à la dimension radiale (D2) du bouchon d'étanchéité (47).
