The connection (1) has a first part (3) with a thread (11) for connecting to the screw thread of a mask. An end side (27) rests tightly against the mask. A second part (5) is joined to the main part of the automatic valve. The first part is rotatably fixed to the second part through which a gas pipe leads (29). The first part is fixed to the second part by a bearing (31) comprising an inner bearing part (33) with outer surface (37) through which the gas pipe leads, and an outer bearing part (35) around the inner bearing part. The inner bearing part has a recess (17) and the outer bearing part has holes (13) in.
