An insulating box device for connecting or terminating high voltage shielded electric cables, each of the cables having an electrical conductor, a cover of insulating material and an electrically conductive shield that surrounds the cover, a part of the shield being removed to allow uncovered the cover, said box device comprising an inner member of insulating material having an elastic portion to cooperate with the cover exposed to firmly grasp the cover in order to increase the dielectric strength or power of the displacement path as length of the cover; and an outer member of electrically conductive elastic material surrounding said inner member along at least a portion of the length of said inner member and having a part to cooperate with the shield to achieve an effective electrical connection therewith. .
