PROBLEM TO BE SOLVED: To provide a compact fluid device connecting structure. SOLUTION: The fluid device connecting structure 50 is maintained to couple first and second connection parts 8, 9 through an annular seal member 31 using a coupling member 51. The first and second connection parts 8, 9 have first connection side tapered surfaces 24, 25 on the outer periphery of end-face-side inside surfaces 20, 21 of first and second fitting grooves 18, 19 in which the coupling member 51 is disposed. The coupling member 51 has split members 52, 53. The split members 52, 53 have first projecting portions 54, 56 in contact with the end-face-side inside surface 20, and second projecting portions 55, 57 in contact with the end-face-side inside surface 21. When drawing the split members 52, 53, the first projecting portions 54, 56 include first connecting side tapered surfaces 69, 74 coming into slidable contact with the first connecting side tapered surface 24. When drawing the split members 52, 53, the second projecting portions 55, 57 include second connecting side tapered surfaces 70, 75 coming into slidable contact with the second connecting side tapered surface 25.
