For joining two cables which have an insulation of a cross-linked linear polymer such as polyethylene, the insulation on each of the two ends to be connected is tapered, the ends of the conductors are then secured to each other, and the joint is wrapped with a tape of the same linear polymer containing a cross-linking agent. The wrapping is enclosed in a tube of relatively rigid material, which is then enclosed in a tube of flexible material. The joint is then enclosed in a casing and simultaneously subjected to heating by an electric heating arrangement and to all-sided pressure exerted by a fluid, which may be a gas or a liquid such as silicone oil.
