Abstract
A plurality of mountings for locating a shadow mask carrying frame in a color cathode ray tube each comprise one mounting element bonded to the tube wall and another mounting element connected to the frame, which together provide a spring-loaded spigot-and-socket connection. One feature is that the element has a portion bonded to the wall of a compatible material and a second portion of a hard material for low-wear. Another feature is that the element which provides the spigot has a recess therearound within the thickness of the wall into which the other element extends in order to save space.
