A device for use in submarine cable systems, particularly for fiber optic cable systems. A water-tight enclosure or housing is provided which is accessible for maintenance purposes. The device, which is of generally tubular shape, provides termination chambers at either end attached to bulkhead members for the introduction of cables and their mechanical termination therein. The fiber optic elements themselves are passed through the bulkhead members in penetrator subassemblies to reach the interior chamber. An axially split cylindrical shell has at least two arcuate members which fit together and nest on circumferential shoulders on the bulkhead members which have radial depths equal to the material thickness of the arcuate members. An outer sleeve slides axially over this assembly, circumferential seals providing water-tight contact between the outer sleeve and the bulkhead members. Axial pressure against the bulkhead members is resisted by axial compression of the split-shell members nested in the bulkhead member annular shoulders. Radially inwardly directed forces are resisted by the outer sleeve itself primarily. A plurality of shear bolts further fixes the outer sleeve (against tensile and torsional forces) to each of the bulkhead members.
