A device for stoppering a container and drawing off a fluid includes a fixed piece, fixed to the container, with a lateral fluid output opening and a passage that allows air to enter. Another, movable piece includes a tube with a lateral fluid output opening. This tube can move in rotation inside the fixed piece and also in axial translation between a maximum "pushed-in" position and an extracted position so that lateral openings can be brought into coincidence through rotating the movable piece. The movable piece has an internal skirt enabling the channeling of fluid toward the output opening to prevent leakage through the passage for the entry of air. The fixed piece includes a guide for displacing the movable piece with respect to the fixed piece from the maximum "pushed-in" position to the extracted position that displays a coincidence of the openings.
