Clamped joint device

A joint device comprising:

• a first tube having a flange at an end;
• a second tube;
• a tubular seal connecting the first tube and the second tube;
• and
• a clamp attached on an outer periphery of the tubular seal, wherein the tubular seal has
• a first end portion engaging with the flange of the first tube,
• a second end portion retaining the second tube therein, and
• an intermediate portion located between the first end portion and the second end portion along an axial direction of the tubular seal,
• the first tube and the second tube are distanced from each other along the axial direction with the intermediate portion of the tubular seal being interposed between the first tube and the second tube,
• the clamp is positioned on the second end portion of the tubular seal with the second end portion of the tubular seal being interposed between the clamp and the second tube,
• the second tube or the clamp has a tab protruding along a radial direction of the tubular seal toward the other of the second tube or the clamp,
• the other of the second tube or the clamp has a slot facing the tab along the radial direction,
• the tubular seal has a slit passing through the tubular seal along the radial direction,
• the tab passes through the slit of the tubular seal and extends into the slot of the other of the second tube or the clamp when the second tube is positioned inside the tubular seal, and
• the end of the first tube having the flange is a distal end of the first tube along the axial direction.
