<P>PROBLEM TO BE SOLVED: To solve the problem that the air-tightness and the pressure resistance can not be secured, namely, due to the inconvenience which is caused by reconnecting a pipe by using a nut after pulling out the pipe and a sleeve from a joint body by removing the nut. <P>SOLUTION: The joint is provided with the joint body 1 having a connection hole 50 and a male screw part 58, the sleeve 3, and the nut 2. The nut 2 is screwed into the male screw part 58 in a state that the pipe 10 and the sleeve 3 are inserted to the connection hole 50. The nut 2 connects the pipe 10 to the connection hole 50 via the sleeve 3. The sleeve 3 is closely fitted to the pipe 10 and the joint body 1 by the screwing of the nut 2. The sleeve 3 is cut at the coupling part 32 coupling a sleeve body 31 and a separation part 33. Accordingly, the sleeve 3 can not connect the pipe 10 to the connection hole 50 after the pipe 10 and the sleeve 3 are pulled out from the connection hole 50 by removing the nut 2. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
