The invention relates to a fresh-air supply system (4) for a submarine, which includes: - a body (22) extending along a longitudinal axis (Z); - a pipe (20) for collecting fresh air, mounted so as to slide along the longitudinal axis inside the body between a retracted position and an extended position; - a valve (26) translatably mobile along the longitudinal axis (Z) between a closed position of an upper end (34) of the collection pipe and an open position of the collection pipe. One head (80) of the valve is placed outside the collection pipe. In the closed position, the head of the valve rests on a seat formed by an end lip (39) of the collection pipe which has a larger diameter than the inside diameter of the collection pipe.
