PURPOSE: A connection portion of pipe for motor vehicles is provided to achieve a superior seal effectiveness and prevent deformation of pipe by using a metallic connection pipe instead of a rubber pipe. CONSTITUTION: A connection is characterized in that a connection end portion of a pipe(10) has an expanded portion(11) of which entrance is coupled with a stop washer(40), a metallic connection pipe(20) has at both outer peripheries thereof a ring packing(30) coupled to the peripheries, both ends of the metallic connection pipe are inserted into the expanded portion of the pipe, and the ring packing at both ends of the metallic connection pipe is arranged to tightly contact an inner periphery of the expanded portion of the pipe. Application of the metallic connection pipe eliminates thermoplastic problem caused by a conventional rubber pipe.
