PROBLEM TO BE SOLVED: To provide a device for preventing MOVEMENT of a pipe fitting, with which the state of preventing a relative change in position between a receive port and an insertion port can be determined based on appearance and which can flexibly cope with a change in design of a pipeline.;SOLUTION: This device 10 for preventing movement of a pipe fitting, which prevents relative movement between a receive port 1 and an insertion port 2 in the pipe axis direction, comprises a cylindrical insertion port side member 16 to be fitted on the peripheral surface of the insertion port 2 and a cylindrical receive port side member 15 to be fitted on over from the peripheral surface of the receive port 1 to the peripheral surface of the insertion port 2. The insertion port side member 16 has a lock portion 12 capable of catching the peripheral surface of the insertion port 2 from the pipe radial direction and a first hook portion 19 extended from the lock portion 12 toward the receive port 1. The receive port side member 15 has an engagement portion 11 to be engaged with the peripheral surface of the receive port 1 in the pipe axial direction and a second hook portion 18 extended from the engagement portion 11 toward the insertion port 2 and bent to be opposite to an end surface 1a of the receive port 1 and structured to be engaged with the first hook portion 19 in the pull-out direction of the pipe fitting.;COPYRIGHT: (C)2009,JPO&INPIT
