An assembly of at least two stacked anti-implosion bands, in which each anti-implosion band 14, 24 comprises suspension elements 15, 25 projecting from the anti-implosion band 14, 24 which surround the adjacent anti-implosion band with clearance. As a result, anti-implosion bands can be stacked in a simple manner for storage and/or shipment, and can be readily unstacked for individual attachment to display tubes.

This invention relates to a color display tube having a color selection electrode which is suspended from the display window by means of pin-shaped members which are inserted in the upright edge 3 of a display window. The pin-shaped members have a spherical free end 16 portion which engages in an aperture of a conical portion of the flat resilient suspension element attached to the corners of the mask. To avoid the flat resilient suspension element from lying against the pin-shaped member, the central axis A of the pin-shaped member forms an angle .alpha. of from 5.degree. to 20.degree. with the X-Y plane.

Disclosed is a cathode ray tube with a metal anti-implosion strap which is electrically connected to the external conductive coating on the conical portion of the tube envelope. The conductive coating extends beneath on adhesive-containing layer provided around the side wall of the display window beneath the metal strap. Positioned between the conductive coating and the metal strap is a metal contact member which electrically shunts the adhesive-containing layer and directly contacts the conductive coating and the metal strap connecting the latter to the conductive coating.
