ABSTRACT:
A pressurized cylinder has a cap mounted thereto. The cap has a skirt wall of corrugated configuration to form a plurality of radially inwardly opening channels which alternate circumferentially with radially outwardly opening channels. A plurality of coplanar, circumferentially extending grooves or slits are formed in the outwardly open channels so as to extend radially completely therethrough. The cap is inserted longitudinally onto the cylinder such that a plurality of tabs carried by the cylinder travel longitudinally within the radially inwardly open channels. Thereafter, the cap is rotated such that the tabs enter the grooves to prevent longitudinal removal of the cap. A yieldable latch locks the cap in its secured position.
