ABSTRACT:
A liquid tight coupling means between a flexible cable conduit and a bulkhead, the coupling means having a tubular sleeve therein of plastics material which defines with the body of the coupling means an annular recess into which the end of the conduit can be fitted. The arrangement is characterized in that the conduit is formed, in a known manner, as a spirally wound tube having a lining of plastics material applied thereto, in that the tubular sleeve defines a passageway through which electrical conductors can be passed without possibility of contact between conductors and conduit end, in that the tubular sleeve has a part projecting beyond the bulkhead engaging end of the body of the coupling means so that conductors can emerge from that end without possibility of contact between said conductors and that end and so that an end face sealing means for the coupling means is provided, in that the sleeve has a conicity so that when the conduit end is inserted into said annular recess the lining of the conduit is caused to grip the sleeve tightly, and in that the sleeve has a spiral of sealing material sealing between the sleeve and the conduit lining.
