Abstract
A sealing gasket for cables, in particular optical or electrical telecommunications cables, for mounting in an inlet of a sealed box for protecting splices and containing a gas under pressure, is provided. The gasket is mounted in a tubular passage secured to the box and includes at least one tubular cylindrical portion of constant diameter having an inner sealing portion connected thereto to bear against the periphery of the cable and to be placed towards the inside of the box. The inner sealing portion is constituted by a tubular frustoconical portion connected to the end of the cylindrical portion and whose smaller diameter end presents an orifice of diameter smaller than the diameter of the cables to be mounted.
