To surely and easily connect with a simple structure while maintaining sealability when two tubes are connected, and also, to easily fix a tube connection structure to a casing.
The tube connection structure 10 includes a tube connection body 14 provided with a through-passage 18 in its inside and an insertion part 20, to which a tube 12 is insertable, at both ends of the through-passage 18. The structure 10 also includes a bracket 16 composed of winding parts 36, which are respectively arranged to the outside of both sides of the insertion part 20 in the tube connection body 14, respectively wound around the outer peripheral face of the tube 12 inserted to the tube connection body 14, and respectively brought into contact with a flange part 28 protruding in the radial direction of the tube at a position offset from the end part of the tube 12 by a prescribed distance, and a coupling part 38 for maintaining the interval between the two winding parts 36 to a prescribed value by coupling the two winding parts 36. A connection state can be maintained by supporting the tube 12 with the bracket 16 after inserting it into the tube connection body 14.
