The invention concerns a sealing part (1) for sealing an optical fibre coupling bush (22) in a fluidtight and dirt-proof manner. The sealing part (1) bears a central sealing element (4) and a sleeve (6) coaxially surrounding the latter. The end-face bevel (5) of the sealing element is adapted in planar manner to the end-face edge (23) of the coupling bush (22). When pressure (A) is suitably applied, the sealing element (4) is urged against the bush (22) and seals the latter. The sleeve (6) embraces the outer surface (24) of the bush (22) in a firmly adherent manner, secures the sealing part (1) in a self- contained rack (21) and seals the bush (22) externally.
L'invention concerne un élément de fermeture (1) permettant de fermer un manchon de couplage (22) de fibres optiques, de manière étanche aux liquides et aux impuretés, qui porte un élément d'étanchéité (4) central et une douille (6) qui entoure ledit élément d'étanchéité (4) coaxialement. L'élément d'étanchéité est adapté par sa face (5) d'about de manière à affleurer le bord d'about (23) de la douille de couplage. L'élément d'étanchéité (4) est comprimé par application d'une pression (A) appropriée contre le manchon (22) qu'il obture. La douille (6) enserre la face extérieure (24) du manchon de manière à y adhérer fermement et fixe l'élément de fermeture (1) dans un support autonome (21) et assure l'étanchéité extérieure du manchon (22).
