In effecting a fluid-tight seal between a plastics part of a cable joint or termination enclosure and the plastics sheath of an electric cable a hole is formed in the wall of said part to form a cable entry of a size appropriate to the cable and a length of the cable is passed through the cable entry so formed. A mould is assembled about the cable adjacent a surface of said part, which mould embraces the cable and has ports for the admission and discharge of molten thermoplastics material, and the mould is temporarily secured to said part of the enclosure. Molten thermoplastics material is injected into the interior of the mould through said admission port and, after a sufficient quantity of molten thermoplastics material has passed through the mould and out of the discharge port to soften the surfaces of the cable sheath and said part of the enclosure, the mould is sealed and the molten thermoplastics material in the mould is permitted or caused to cool and make an effective bond with the cable sheath and with said part of the enclosure.
