ABSTRACT:
An enclosure is assembled about an electric cable joint or termination by applying about the cable or cables a plastics sleeve slit therethrough its length and enclosing the adjacent pair of longitudinal edges of the sleeve in a mould which has ports for the admission and discharge of molten thermoplastics material. Molten thermoplastics material that is compatible with the plastics material of the sleeve and that is at a temperature appreciably above the softening point of said material is injected into the mould through at least one port and, after a sufficient quantity of molten thermoplastics material has passed through the mould to soften the surfaces of said longitudinal edges, the molten thermoplastics material in the mould is permitted or caused to cool and make an effective bond between said longitudinal edges. The sleeve is then sealed to adjacent separately formed end parts of the enclosure.
