PROBLEM TO BE SOLVED: To provide a resin pipe connection joint for securing the flow amount of fluid matching to the inner diameter of a resin pipe while giving a come-off preventing effect to the resin pipe. SOLUTION: The resin pipe connection joint has an engaging tooth portion formed on a connection cylinder portion into which the resin pipe 100 is inserted, with cutting work for engaging with the inner periphery of the resin pipe 100 to prevent the come-off of the resin pipe 100. The connection cylinder portion 10 is formed with a thin pipe, and the engaging tooth portion 20 is separated from the connection cylinder portion 10 and held to be fitted to an annular recessed portion 11 formed in the pipe wall of the thin pipe. The inner diameter of the annular recessed portion 11 is made larger than the inner diameter of the connection cylinder portion formed by cutting the engaging tooth portion 20 so as to approximate the inner diameter of the resin pipe 100.
