The device consists of a contact pressure element (2,3) and an abutment (15), so that two body parts (1,13,14) can be pressed together. The first part has a mainly trough-shaped profile, and the contact pressure element engages on an outer wall (4,5) of that part. The second body part engages at least partially on the inside of the first part, and the abutment is partially located inside the first part. The surface of the second body part away from the contact with the first part, engages on a contact face (16,17) of the abutment.
