A first connecting element (,) with a conical supporting bore (,) is adapted to contact the outer conical face (,). A second connecting element (,), in the form of a connecting body, is provided to thread onto the first connecting element (,), in the form of a nut. The second connecting element (,) has a counter sealing face (,) in the form of a conical bore. A sealing element (,) cooperates with the first conical bore (,) of the connecting portion (,) and with the counter sealing face (,) in the form of a conical bore of the second connecting element (,). The sealing element (,) has a first outer conical sealing face (,) and a second outer conical sealing face (,). The faces (,) are designed to match the first conical bore (,) and the counter sealing face (,) in the form of a conical bore.
