PURPOSE: A sleeve connection structure for simultaneously coupling both sides of a synthetic resin threaded pipe to a sleeve is provided to stably maintain the coupled state of synthetic resin threaded pipes using an outer cover. CONSTITUTION: A sleeve connection structure for simultaneously coupling both sides of a synthetic resin threaded to a sleeve comprises synthetic resin threaded pipes(10,11), a sleeve(20), and rubber rings(30,31). The synthetic resin threaded pipes comprise a forward female screw part(12) and a connection plane(11a). A reverse female screw part(13a) of a connector(13) is integrally connected to the connection plane. The sleeve comprises forward and reverse male screw parts(21,22) and a cutoff wall(28). The forward and reverse male screw parts are coupled to the forward and reverse female screw parts of the synthetic resin threaded pipes. The cutoff wall is formed between the forward and reverse male screw parts. The rubber rings are installed in both sides of the cutoff wall.
