Connector and fluid supply system

A connector comprising:

• a tube configured to be arranged in an interior of a soft tubular member;
• a tubular body having an inner wall surface configured to, together with an outer wall surface of the tube, sandwich the soft tubular member when the tube is arranged in the interior of the soft tubular member;
• a balloon, configured to be arranged on the outer wall surface of the tube or the inner wall surface of the tubular body, and radially expand for performing sealing (i) between the soft tubular member and the inner wall surface of the tubular body and (ii) between the soft tubular member and the outer wall surface of the tube;
• and
• a concavity is formed in the inner wall surface of the tubular body at a part contacting the expanded balloon, or a concavity is formed the outer wall surface of the tube at a part contacting the expanded balloon.

• and
• a coupling member for coupling together the tube and the tubular body such that the tubular body is movable relative to the tube.
