A cable connector for connecting cables and the like to a partition or housing, provides improved grounding and utilizes an elastomeric seal to prevent leaks. One size of connector can take a wider range of cable sizes than known connectors. The connector comprises a rigid tubular housing with external attachment means for attachment to an aperture in a partition, the housing having passage therethrough for a cable and a curved shoulder in the passage. A tubular seal having a cylindrical inner surface, a frusto-conical outer surface extending from a small end, a curved lip at the small end where the outer surface and the inner surface join, the curved lip adapted to sit against the curved shoulder in the passage, and a threaded cover to push the seal so that the curved lip of the seal is swivelled inwards and is adapted to contact the cable in the housing.
