AIR SAFETY CONNECTOR Russian patent published in 2014 - IPC F16L37/08 

FIELD: machine building.

SUBSTANCE: connecting assembly for a compressed air circuit has a fixing device for detachable connection of the first and the second subassemblies located in the corresponding ends of the first and the second air main lines. The first air main line is connected to a tool that can be operated with compressed air, and the second air main line is connected to a compressed air source. A valve device controls a compressed air flow between the first and the second air main lines. The valve device is connected to the second subassembly and is capable to move with sliding between the first position in which it allows compressed air passage and the second position in which it does not pass any compressed air flow. The connecting assembly has a locking device to prevent disconnection of the first and the second subassemblies when the valve device is in the first position. The fixing device includes the first and the second fixing cams. The locking device includes a pair of locking clutches.

EFFECT: invention improves connection reliability of a compressed air supply line.
