PROBLEM TO BE SOLVED: To provide a resin pipe connecting structure having improved sealing performance against gas easy to permeate such as hydrogen gas. SOLUTION: A connection pipe body 20 is connected to a resin pipe 30 by pressing the resin pipe 30 in the connection pipe body 20 and further thrusting the resin pipe 30 thereto with a reinforcing sleeve 40. An inner layer 31 resistant to hydrogen gas, a barrier layer 32 permeation resistant to the hydrogen gas and an outer layer are laminated on the resin pipe 30. On the outer periphery of the resin pipe 30, the reinforcing sleeve 40 is provided for thrusting the resin pipe 30 toward ring protruded portions 22, 23, 24. The reinforcing sleeve 40 thrusts the resin pipe 30 in the condition that the resin pipe 30 is pressed in the connection pipe body 20. The ring protruded portions 22, 23, 24 have front ends 22c, 23c, 24c forced through the inner layer 31 and bitten into the barrier layer 32. COPYRIGHT: (C)2005,JPO&NCIPI
