The invention relates to a device for fastening a cathode ray tube on a covering frame, in the case of which a flat flange which is fastened on the cathode ray tube and is provided with a bore is screwed to the covering frame by a screw, via an internal thread. Arranged between the covering frame and flange is a compensating element which, in a position which is determined by the cathode ray tube butting against the covering frame, can be fixed in relation to the covering frame in that the compensating element interacts with an internal-thread-containing guide part of the covering frame. By virtue of the screw being screwed into the guide part, the compensating element, by virtue of the guide part being widened in the region of said compensating element, can be clamped firmly on the guide part in that the guide part is of tubular configuration with at least one longitudinal slit and is enclosed by the compensating element, against which the guide part presses, when the screw is screwed in, with the longitudinal slit or slits widening in the process.
Device (5) for fastening a cathode ray tube (1) on a covering frame (4) in which a flat flange (3), which is fastened on the cathode ray tube (1) and is provided with a bore, is screwed to the covering frame (4) by a screw (7), there being arranged between the covering frame (4) and the flange (3) a tubular compensating element (6) which, in a position which is determined by the cathode ray tube (1) butting against the covering frame (4), can be fixed in relation to the covering frame (4) in that the compensating element (6) interacts with a guide part (8) of the covering frame (4), the guide part (8) having an inner tube defining an opening and an outer tube (10) coaxial with the inner tube, with an annular space which is located between the two tubes and is essentially filled by the tubular compensating element (6), characterized in that the inner tube (9) is provided with at least one longitudinal slit (16, 17), and the compensating element (6) can be clamped firmly by the inner tube when the screw (7) is threaded into the inner tube such that the inner tube widens to clamp against the compensating element (6).
