To provide a turn connector improving a holding characteristic so as to easily grip the connector by a tube end member.
A turn connector 701 is a turn connector of two-piece structure, to be constituted by a turn main body end 702 extending a tube extension part 706 and a turn end 750 which can insert the tube extension part 706. In an end part position 710 of the tube extension part 706, a flange tip end 707 is provided, which has flexibility with pressing in possible rotatably while into close contact relating to a hole 760 of the turn end 750. Between an end of a large diametric part 723 of the tube extension part 706 and a bottom of a hole 725 in a central part 722, an O ring 730 of dimension sufficient for giving a slip while holding air-tightness is interposed. In the turn end 750, except in a part its end part 755 is brought into contact with a flange tip end 707, external dimension is formed similarly to the turn main body end 702.
