Abstract:
A sealing device to establish a seal between a partition and at least one cable passing through a hole in said partition, said sealing device comprising:two half-shells forming a cylindrical body completely surrounding said at least one cable and being secured to said partition at said hole, said cylindrical body having a female screwthread at a first end, and in a region located distant from said female screwthread, an annular internal shoulder; a sealing joint between said cylindrical body and said partition; and sealing means for filling a space between said at least one cable and said cylindrical body and immobilizing said at least one cable and said cylindrical body relative to each other, said sealing means comprising at least one flowable elastic sealing gasket surrounding said at least one cable; a radial gripping device comprising an elastically deformable split ring that surrounds said at least one flowable elastic sealing gasket and engages said cylindrical body in axial abutment against the annular internal shoulder of said cylindrical body, said elastically deformable split ring having a radially retractable skirt that is radially retractable in a substantially uniform manner about a circumference of the radially retractable skirt under an influence of an axial gripping force; and an axial gripping device exerting the axial gripping force, said axial gripping device comprising a resiliently deformable split collar that slides axially in said cylindrical body and has a central hole with a conical surface facing toward a free end of the radially retractable skirt, and two half-nuts forming an externally screwthreaded sleeve-nut that surrounds said at least one cable, is screwed into the female screwthread of said cylindrical body, and presses axially against said split collar, said conical surface pressing against the free end of the radially retractable skirt to force said radially retractable skirt to radially retract, so as to compress, and cause said sealing gasket to flow to fill said space between said at least one cable and said cylindrical body.
