The slide sheath comprises a slide body with which a brake device is pivotably arranged. A first arresting element, pref. integrated with the slide sheath body, is provided for working in conjunction with a first transversally orientated surface of the long anchored element. In relation to the slide sheath body a second arresting element is movably arranged which works on conjunction with a second transversally arranged surface of the long anchored element. The second arresting element has a potential slide surface which exceeds 5 mm in its extent in the slide direction and slide surfaces in the vicinity of the ends curve away from the plane in which the sliding movement occurs. |
