Abstract
In a color picture tube, the shadow mask is suspended in a way such that the pins inserted into the rim portion of the faceplate are aligned vertically in relation to the axis of symmetry of the color picture tube. The free ends of the pins are of spherical design, and comprise a conical part. Two-piece, trapezoidal hold members for the shadow mask rest on the pins. Each of the hold members is resiliently pressed upon the pins by a locking spring.
