The invention relates to a connector (1) for locking and orientable connection for medical gas, said tip comprising at least one connecting body (2), a ring and a pin (5) keying and locking, the ring being slidable on the connecting body (2) while being integral in rotation with the connecting body (2), a compressible spring (6) pushing the ring forward, the pin (5) being immobilized in translation on the connecting body ( 2) while being free in rotation, disengageable engagement means for securing in rotation the connecting body and the pin in the setting position. According to the invention, the ring consists of an operating ring (3) and a tubular skirt (4) interlocking one inside the other and movable in axial translation with respect to the other, the skirt (4) attached to the spindle (5) having an inner face (41) notched (42), the operating ring (3) having a tubular portion (31) provided externally with notches (32), the notches (32) of the operating ring (3) and the notches (42) of the skirt (4) forming the disengageable engagement means by axial translation between the operating ring (3) and the skirt (4), the operating ring (3) slidable back and forth on the connecting body (2) while being integral in rotation with the connecting body (2) being pushed by the spring (6) into the skirt (4) for engagement, the spacing of the operating ring (3) of the skirt (4) causing the disengagement. L'invention concerne un embout (1) de connexion verrouillable et orientable pour gaz médical, ledit embout comportant au moins un corps de liaison (2), une bague et une broche (5) de détrompage et verrouillage, la bague pouvant coulisser sur le corps de liaison (2) tout en étant solidaire en rotation avec le corps de liaison (2), un ressort (6) compressible poussant la bague vers l'avant, la broche (5) étant immobilisée en translation sur le corps de liaison (2) tout en y étant libre en rotation, un moyen de mise en prise débrayable permettant de solidariser en rotation
