A joint adapted to ensure the interconnection of two electrical cables, each cable including a central conductor, an insulation layer (1), a semi-conductive coating layer (2), a metallic cable screen (3) and an outer cable jacket (4). The joint includes mechanically shrink-fittable materials adapted to ensure, when shrunken, a dielectric continuation (5) of the insulation layer, a continuation of the cable screen by a metallic joint screen (6), and an outer protection (7). The invention more particularly concentrates on an improvement of the screen continuation of the cable. The joint includes therefore, a layer of conductive material (9) placed underneath the metallic cable screen (3) at the location where this cable screen is in contact with the joint screen (6). As a result, the joint shows a relatively low electrical resistance between the cable screen and the joint screen, is cost effective and is easy to install. It can furthermore withstand, after installation, the impact of sharp heavy items without damaging either the joint or the cable because there are no cutting items under the outer cable jacket (4).
