An end bayonet shutter is proposed, which consists of a body and a cover on which the bayonet connection elements are made. The cover is installed with the possibility of rotation around its axis on the hinged lever. A blocking unit is installed on the cover, which consists of a movable handle that blocks rotation of the cover towards the opening and is connected with a pressure relief valve, and a blocker containing a stem that blocks the movement of the handle when there is pressure in the internal cavity of the valve. The blocking unit itself is also offered as an independent device.
