PROBLEM TO BE SOLVED: To enable the connection to a successful sealing performance independently of the size in the pipe diameter of a connection pipe, and enable the adequate connection without slipping-off of the connecting pipe by certainly pushing each slipping-off ball against the outside of the connecting pipe by clamping force such as a bolt to connect and fix a joint main body and a flange body. SOLUTION: There is provided with a ring-like packing to hermetically seal by compressing between the connecting pipe outside, the joint main body and the flange body in the integrally connecting of the joint main body with the flange body, and a slipping-off protection mechanism to prevent the pipe from slipping off by pushing a plurality of slipping-off balls against the outside surface of the connecting pipe in a taper surface formed in the inside surface of the flange body.
