Summary:To provide a fluid pipe joint device capable of confirming a required amount of fastening of a connection nut, and capable of preventing loosening of the connection nut by maintaining the required amount of the fastening.SOLUTION: A fluid pipe joint device 3 includes a fluid pipe joint 3a and a locking tool 20. The fluid pipe joint 3a includes a first joint member 5 and a second joint member 10. The first joint member 5 includes a first connecting portion 7, and the first connecting portion 7 has a first shaft 8 and a connection nut 9. The second joint member 10 has a second shaft 13 (second connecting portion 12). A male screw 13a is formed on an outer periphery of the second shaft 13, and the first connecting portion 7 and the second connecting portion 12 are connected with each other by screwing of the connection nut 9 and the male screw 13a. The locking tool 20 includes a nut abutment portion 20a abutting on a backward side end face 9a of the connection nut 9, and regulates movement of the connection nut 9 to the male screw 13a in a retreat direction 22 in a state of being attached to the fluid pipe joint 3a.SELECTED DRAWING: Figure 3 【課題】連結ナットの必要量の締め込みを確認することができ、かつ、必要量の締め込みを維持して連結ナットの緩みを防止することができる、流体管継手装置を提供する。【解決手段】流体管継手装置３は、流体管継手３ａと、緩み止め具２０とを備える。流体管継手３ａは、第１継手部材５と第２継手部材１０とを備える。第１継手部材５は、第１結合部７を備え、その第１結合部７は、第１軸部８と連結ナット９とを有する。第２継手部材１０は、第２軸部１３（第２結合部１２）を備える。第２軸部１３の外周には、雄ネジ部１３ａが形成されて、連結ナット９と雄ネジ部１３ａとの螺合により、第１結合部７と第２結合部１２とが互いに結合される。緩み止め具２０は、連結ナット９の後方側の端面９ａに当接する、ナット当接部２０ａを備え、流体管継手３ａに取り付けられた状態で、雄ネジ部１３ａに対する連結ナット９の、後退方向２２への移動を規制する。【選択図】 図３
