PROBLEM TO BE SOLVED: To provide a connection arm attachment structure for a tube disconnection prevention fixture capable of eliminating threading and drilling, never falling into pieces of respective fixture pieces in disassembling, and facilitating fitting work. SOLUTION: In this tube disconnection prevention device 25, two halves of the fixtures 32A, 32B, and 34A, 34B are attached at a coupling portion which engages a socket tube 31 and an insertion tube 33 with expandability and flexibility to be tightly tightened, and the fixtures of the respective tubes are connected by a connection arm 35 with each other to prevent removal between the tubes. An engagement portion 30 of the joint arm 35 consisting of a forked standing piece 43 extended in an outer periphery direction, horizontal pieces 44 extending in the same direction as the tube axis from the standing piece 43, and a connection piece 45 connecting the horizontal pieces 44 with each other is provided at an outer periphery surface of the respective two halves of the fixture pieces. A head portion 35A of the connection arm of which the top end is formed in a T-shape is engaged with the engagement portion 30. COPYRIGHT: (C)2005,JPO&NCIPI
