PROBLEM TO BE SOLVED: To provide a structure of a gas-type quick coupling unit fixing frame and its application method, wherein a back frame is formed totally larger than a gas-type quick coupling unit hole to improve the durability to the pulling-out or the pushing. SOLUTION: This fixing frame is composed of a front frame 1 located at a back side of a square frame body 2 and having screw receivers 3, 4 on left and right of an upper frame 2a, the back frame 11 having an opening part 13 formed by cutting one corner of a square frame body 12, and having screw holes 14, 15 at positions opposite to the screw receivers 3, 4 at the front frame 1 side, and two fixing screws 5, 6 inserted from the screw receivers 3, 4 of the front frame 1 side and capable of being engaged with the screw holes 14, 15 at the back frame 11 side, at their tip sides. In mounting the fixing frame, two fixing screws 5, 6 are inserted into the screw receivers 3, 4 of the front frame 1, and the tips of the fixing screws 5, 6 are engaged a little in the screw holes 14, 15 at the back frame 11 side to connect the front frame 1 and the back frame 11. Then the back frame 11 is entered into a back side of a wall 102 over a lower edge of the gas-type quick coupling hole 102 through the opening part 13 of the back frame 11 and positioned, and then the fixing screws 5, 6 are screwed in, whereby a clearance between the back frame 11 and the front frame 1 is narrowed and the fixing frame is fixed to the wall 102.
