Summary:A joint adapted to ensure the interconnection of two electrical cables, each cable comprising a central conductor, a insulation layer (1), a semi-conductive coating layer (2), a metallic cable screen (3) and an outer cable jacket (4). The joint comprises mechanico retractable materials adapted to ensure, when shrinked, a dielectric continuation (5) of the insulation layer, a continuation of the cable screen by means of 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 comprises 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, impact of sharp heavy items without damaging neither the joint nor the cable because there are no culling items under the outer cable jacket (4).
