ABSTRACT:
A device for quickly coupling and decoupling conduits comprises a fitting ving spaced exterior surface concavities in an annular array and axially facing shoulders at the concavities, the fitting defining a bore open to one conduit. The device has a tube fixed to another conduit and sealed slidingly with the bore, and also has a receptacle translatable along the tube for rotatably receiving the fitting. The receptacle defines an opening where the receptacle enters, an orifice through which the tube passes and an annuler channel about the fitting. A spring axially mobile in the channel interferingly girds the fitting and has a first and second segments. The second segments protrude closer than the first segments to the device's central axis and fit the concavity. The device has a pin in the channel protruding radially inward further than a zone of the second segment but not as far as a zone of the first segment, whereby the pin is usable to selectively prevent spring rotation relative to the receptacle.
