An assembling tube for connecting a resin pipe is provided to combine the pipe easily by sealing efficiently and restricting over coupling, and to reduce maintenance cost by checking connection state visibly. A resin pipe connecting tube is composed of a cylindrical resin pipe(150) passing chemicals, a connector(100) having a male screw part combined with a nut(110) by thread, a protruded part formed by extending the male screw part and an inner assembling part extended to form a staple-shaped space in a lower part of the protruded part and contain the resin pipe, and the nut composed of a female screw part combined with the male screw part and a wedged protruded part extended from the end of the female screw part to form a staple-shaped space and to store the protruded part and combined with the connector for pressing an outer surface of the resin pipe. First and second auxiliary rings(120,130) are attached or detached from the connector and the outer surface of the nut to check connection of the resin pipe.
