<p>A method of manufacturing a longitudinally watertight cable in which a sealing mixture of a vulcanisable silicone rubber, a diluent and a filler is provided in the cable core and between the cable core and the sheath, which mixture, after curing, forms a water-tight stopper. According to the invention, and a bivalent or trivalent metal salt of a higher fatty acid or a mixture of higher fatty acids is used as a filler. A sealing mixture is preferably used in the method which comprises 15-25% by weight of a multicomponent silicone rubber, 35 - 45% by weight of silicone oil and 35 - 45% by weight of calcium stearate.
