A safety cap for protecting against damage and tampering the shut-off valve of a high-pressure gas cylinder. The safety cap has a female threaded base bracket which is engaged with the male-threaded neck ring of the gas cylinder. Hinges carried by the base bracket and symmetrical shield halves pivotally mount the shield halves. Positive-lock hinge clamps maintain the shield halves in abutting closed position to protect the shut-off valve. The clamps can be unclamped and the shield halves fully opened to provide full and unrestricted access to the shut-off valve. |
