PROBLEM TO BE SOLVED: To provide an inexpensive pipe connection structure for easily and reliably connecting pipes to each other with simple operation without slip-off. SOLUTION: The connection structure comprises a male pipe 10 having a male side flange 11, a female pipe 20 having a diameter enlarged portion 21 and a female side flange 24, a seal ring 30, and a pipe clamp 40. The pipe clamp 40 has a pair of semi-cylindrical members 41, 42 which are connected at their ends to each other via a hinge 43 and which have clips 44, 47 at the other ends. On the inner periphery of each semi-cylindrical member, there are a male side rib 49 which engages with the male side flange 11, a support portion 51 which engages with the female side flange 24, and a female side rib 50 which engages with the diameter enlarged portion 21. The male side rib 49 and the female side rib 50 do not overlap each other in view from the axial direction, and the width of the male side rib 49 is wider than that of the female side rib 50.
