PROBLEM TO BE SOLVED: To provide a pipe-connecting joint of a refrigeration cycle device for disabling reuse of the pipe-connecting joint or a flare part of a pipe in reinstallation work or disabling reuse of the flare part of the flare part although enabling re-piping after wrong piping. SOLUTION: In relation to a pipe-connecting joint of a refrigeration cycle device for connecting one-side refrigerant pipe to the other-side refrigerant pipe by screwing a nut member fitted onto the other-side refrigerant pipe having the flare part at an end to a connection opening body with the one-side refrigerant pipe connected thereto, this pipe-connecting joint of a refrigeration cycle device has a reuse prevention means for preventing reuse of the flare part of the other-side refrigerant pipe.
