Sealing device for the passage of a cable between two volumes at different pressures, particularly for the penetration of a submarine cable subjected to dynamic stresses into a volume at a pressure less than the pressure of the surrounding water, comprising a gland with at least one packing element in the form of an annular body made of an elastomer, compressed axially in a box for the purpose of it being clamped radially inward against the cable jacket and outward against the box. The annular body (6) of the packing element closest to the high-pressure volume is extended, along its inside diameter, toward said volume by a sleeve (19) which, in the manner of a cuff, surrounds and grips the cable jacket from the inside of the box (2) of the gland right into the high-pressure volume. Preferably, said sleeve (19) has, at least at its free end, in the relaxed state, an inside diameter less than the outside diameter of the cable jacket (3). <IMAGE> |
