Abstract
Abstract The invention concerns a process and a device ensuring the fixation on the neck of a cathode tube of the deflection yoke of the tube. According to the invention, the deflection yoke 3 is fixed after its positioning has been determined between a fixed abutment 9 which may be adjustable in position and an elastic abutment 6 which presses the yoke 3 against the abutment 9. The invention applies especially to tubes adapted to be fitted to color television receiver appliances.
