A cable fitting for ship bulkheads which can be installed after the cable is already in place and testing of the cable connections completed. All parts of the fitting are split diametrically and fitted around the cable from the outside. A housing has a base which is secured to the bulkhead. The cable extends through adjacent circular and frustoconical openings in the housings. A frustoconical compression gland is mounted in the frustoconical opening in the housing. A nut is tightened on the housing to compress the gland inwardly into engagement with the cable. A loosely mounted washer in the nut prevents twisting of the gland. Sealing means are provided in all portions of the fitting.
