PROBLEM TO BE SOLVED: To provide a flare tube fitting facilitating assembly between a plug and a fitting part and preventing outflow of an operating fluid. SOLUTION: The flare tube fitting for connecting an operating cylinder 350 and a hydraulic pipeline 305 and preventing outflow of the operating fluid, includes the plug 310 formed with an insertion hole 312 into which the hydraulic pipeline 305 is inserted, and a groove 314 on the outer peripheral surface of a lower stage; the fitting part 330 formed with a coupling groove 332 on the inner peripheral surface of an upper part so as to be fittingly coupled to the plug 310, a through hole 334 for inserting the hydraulic pipeline 305, and a fixing protrusion part 336 on the inner peripheral surface of the through hole 334 to securely settle the hydraulic pipeline 305; and a resilient coupling means 320 provided at the groove 314 of the plug 310 so as not to detach the plug 310 from the fitting part 330.
