CA 2307149

The present invention is directed to a 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 of the packing element closest to the high-pressure volume is extended, along its inside diameter, toward said volume by a sleeve which, in the manner of a cuff, surrounds and grips the cable jacket from the inside of the box of the gland right into the high-pressure volume. Preferably, said sleeve has, at least at its free end, in the relaxed state, an inside diameter less than the outside diameter of the cable jacket.
