Convergence correction device for a color display tube comprising a rolled-up flexible support provided with two convergence correction coil systems at its inner surface as well as its outer surface. The coils of each system are of the spiral-shaped type and are interconnected via metallized apertures by means of an electrically conducting strip at the opposite circumferential surface. Dependent on the specific configuration, the flexible support is wound once or twice around the neck of the display tube.
