Electrical conductors (3) are led out of the front section of the rear connection part (4a), wherein the hose (1) does not cover the front section of the rear connection part (4a). A protective envelope (2) for the electric conductors (3) is attached at the inner wall of the hose (1). Flanks of the rear connection part (4a) transition into the projection (4c) formed for the receiving of a coordinated end of the protective envelope (2) as well as closed at the front end. An axial slot (4b) is formed in the connection sleeve (4).
