ABSTRACT:
A valve for pulmonary medical use includes first and second valve portions which are coupled together so that they can rotate with respect to each other and feed oxygen or suction to a patient. The two portions are held together by locking means made up of male and female portions which engage each other in such a way as to pull the two portions of the valve toward each other to hold them in tight coupling.
