Protection device for a container for pressurized gas

A protection device for a container for pressurized gas, comprising a valve body which is provided for dispensing the gas which is contained in the container, the protection device comprising a main body which is configured so as to at least partially close the valve body and a coupling element comprising a pair of arms, the coupling element being rotatably connected to the main body about a rotation axis so as to be positioned in two different configurations, a first closed configuration, in which the arms are directed towards the valve body and/or the pressurized container, and a second open configuration, in which the arms are in a remote position with respect to the main body, the protection device being characterized in that the main body comprises an abutment element which extends in the direction away from the main body, the abutment is element being configured in such a manner that, when the coupling element is in an open configuration, a receiving cavity is defined between the abutment element and the arms and is configured to receive a bar-shaped element, having a circular or oval or rectangular cross-section or with a regular polygon shape, in such a manner that the bar-shaped element is in contact with both the abutment element and the arms, wherein the abutment element comprises an abutment surface which has a curved surface, wherein each arm defines an additional abutment surface which extends along a circumferential arc, and wherein the additional abutment surface extends over an angle (β) less than 90°.
