An improved cathode ray tube consisting of a panel member coated on its inner surface with a phosphor layer, and having a funnel member and a neck member with an electron gun mounted therein in which an image is formed on the phosphor layer by an electron beam emitted from the electron gun and comprising fittings located at the corners of the panel member with a tension band tightened to the panel member over the fittings with each of the fittings having first portions substantially parallel to the tubular axis of the cathode ray tube and second portions extending from the first portion and extending in the direction perpendicular to the tubular axis of the tube to form a substantially L-shaped member in cross-section. The first portion has curved surfaces which conform with a peripheral wall surface of the cathode ray tube at its top end portions and indented portions which distribute bearing stresses of a tension band uniformly over the tube to eliminate problems arising during explosion.
