Abstract
A coupling has first and second tube portions joined by a control collar that is rotatable to axially position the first and second tube portions in an installed position, a locked position and in a blow-off position. In the locked position, the tube portions are axially inserted and rotated and locked together by a biasing spring against separation and an O-ring member on one tube portion seals against the other tube portion to seal the tube portions together to prevent fluid leakage therefrom when in their locked position. The other tube portion includes a relief port which is opened for safety blow-off of pressure when the one tube portion is positioned in the blow-off position.
