A protective structure is provided for a gas cylinder assembly comprising a gas cylinder body and a valve. The gas cylinder body includes a base and a neck to which the proximal end of the valve can be connected when in use. The protective structure includes first and second structural sections, wherein the first structural section is connectable to the valve such that the second structural section is spaced from the valve by the first structural section. Moreover, in use, the second structural section is configured to impart an impact force to the first structural section, and the first structural section is configured to deform against the second structural section in response to the impact force to reduce the peak impact force on the valve do. |
