The present invention relates to a towing pipe assembly including a buffer beam (100) on which a towing pipe installation hole (110) is formed; a towing pipe coupler (200) inserted by passing through the towing pipe installation hole (110), including a flange locked by the front end of the towing pipe installation hole (110) on one end, and integrated with one end of a towing pipe; and a towing nut (300) including a flange-shaped protruding ring (310) on one end and the other end opposite to the protruding ring (310) screw-coupled to one end of the towing pipe coupler (200) and adhering to the buffer beam (100). Provided is the towing pipe assembly characterized by a fact that the length (R) of the towing pipe coupler is fixated while the length (L1, L2, L3) of the towing nut (300) is varied in accordance with a vehicle model. The present invention is capable of simplifying a coupling structure of the towing pipe made of a steel material and the buffer beam made of a resin material, reducing the number of coupling processes while improving a coupling force, and commonly using a part of the towing nut while reducing expenses, thereby obtaining an effect of improving maintenance convenience.
