Normally, compressed air coupling plugs lock inside a coupling housing. Decoupling must consequently occur by releasing said plugs counter to the friction forces existing between the plug and the housing. This requires force and the plug may not relieved of pressure when decoupled. The invention works with a locking element (2) which is mounted in a coupling housing (1). The plug (5) and the locking element (2) are provided with reciprocally corresponding locking means (24, 52; 28, 56) whereby the locking element (2) can be pivoted for decoupling without the plug (5) pressing on the housing (1), thereby enabling large caliber tubing, such as those used with construction compressors, to be coupled by hand without tools.
