The present invention relates to a connecting device with a function for preventing the separation of a refrigerant pipe for air conditioner, and, especially, to a connecting device with a function for preventing the separation of a refrigerant pipe for air conditioner, wherein the connecting device having a holder, which is inserted into the outer surface of the refrigerant pipe and burrows spikes into the refrigerant pipe when moving forwards and pressurized by being interlocked with the tightening operation of a fixing nut, fixes the refrigerant pipe continuously and firmly even if instantaneous pressure is generated when the air conditioner is operated, so that not only the separation of the refrigerant pipe from the inside of the connecting device is prevented, but also airtightness deterioration due to bending or unbending the refrigerant pipe in a piping work is prevented. A connecting device with a function for preventing the separation of a refrigerant pipe for air conditioner according to the present invention comprises: a connecting unit of which both ends have male threads based on the outer center of the connecting unit and the inside has a coupling hole and a flow path for the flow of a refrigerant; a holder of which the inside has a longitudinal coupling hole for coupling the refrigerant pipe to the holder and the front end has at least two cutting parts and at least two spikes formed along the circumference thereof at predetermined distances; and a fixing nut positioned at one side of the holder by being coupled to the refrigerant pipe, having female threads formed on the inner surface thereof and corresponding to the male threads, and having a washer supporting surface at one inner end thereof, wherein the refrigerant pipe, which is firmly fixed by pressurizing and burrowing the spikes of the holder into the outer surface of the refrigerant pipe when the holder is interlocked with the tightening operation of the fixing nut, can be prevented from being separated from the connecting device even if instantaneous pressure is applied to the refrigerant pipe. |
