A connection structure of a synthetic resin conduit is provided to improve seal against water more by enhancing engagement force of a first combining tool and a second combining tool and then constraining them not to be separated from each other. A first combining tool(110) extended at specific length on one side of a tubular body of a synthetic resin pipe. A combining protrusion(114) is protruded inside the tip of the first combining tool. A incised groove is formed horizontally by specific length from the tip of the first combining tool. A first combining groove(116) having a specific depth is formed on the outer surface of the first combining tool. A second combining tool(120) is extended by specific length on the other side of the synthetic resin pipe. A watertight groove(122) having a specific depth is formed on the outer surface of intermediate end of the second combining tool. A retaining groove(124) in which a coupling protrusion(114) of the first combining tool is accommodated in the tip of the second combining tool. A second coupling groove is formed inside the retaining groove having a protrusion(126) therebetween.
