Abstract: An elongated waterproof enclosure for spliced telephone cables is provided by a two-part molded resinous housing that provides openings for one or more cables at opposite ends. A one piece resilient sealing gasket includes longitudinally slitted tubular gaskets at the ends to snugly receive individual cables side by side. The grommets at each end are formed integrally and connected by flat connecting pieces arranged to be transverse to opposed narrow edges of the mating opposed housing portions. The narrow edges when clamped together pinch and seal the flat pieces. Housing ends conforming to the grommets also have opposed narrow edges which, when clamped together, pinch the grommets and provide a seal. The housing pieces are preferably connected along one side by an integral molded hinge offset from the opposed longitudinal edges to give the seal clearance. At the opposite side of the housing, offset from the edges, are rigid flanges molded integrally with the housing parts.
