A sealing device allows the passage of a submarine cable. The cable including a cable jacket, from a high-pressure volume corresponding to surrounding water into a low-pressure volume, particularly for a cable subjected to dynamic stresses. The sealing device includes a gland box system with at least two individual packing elements, each of the at least two individual packing elements in the form of an annular body made of an elastomer, having an inside diameter, and compressed axially within a gland box for the purpose of it being clamped radially inward against the cable jacket and outward against the gland box. In addition, the sealing device includes washers being inserted within the gland box between the at least two individual packing elements. The individual packing element of the at least two individual packing elements closest to the high-pressure volume includes an integral sleeve portion.
