PROBLEM TO BE SOLVED: To provide a joint mountable/demountable on/from a pipe body such as hose with easy operation. SOLUTION: A protruded portion 14 is formed on the peripheral face of a joint body 12, and a first bagged portion 18 formed of a rubber and filled with fluid 24 is arranged on one side (on the opposite side to the hose 30) of the protruded portion 14. On the other side of the protruded portion, a second bagged portion 20 formed of a rubber and filled with the fluid 24 is arranged between the joint body 12 and the hose 30. The first bagged portion 18 and the second bagged portion 20 are communicated with each other via a connection pipe 22. A nut 16 is provided on a screw portion of the joint body 12, and the nut is fastened to the side of the protruded portion 14 to crush the first bagged portion 18. Thus, the fluid 24 moves through the connection pipe 22 to the second bagged portion 20, and then the second bagged portion 20 is expanded to thrust the inner wall of the hose 30.
