PURPOSE: A connector pipe is provided to achieve improved soundproof and heat-insulating effects through a sealed air layer formed between the inner and outer pipes. CONSTITUTION: A connector pipe(32) comprises inner and outer pipes. An air layer(35) is formed between the inner and outer pipes and sealed by applying an adhesive on a sealing ring(36) and inserting the sealing ring. A packing mounting part(39) is formed on an interior side of the outer pipe(33), in which a packing(28) is inserted. A gland(23) with an angled surface(25) is installed on a nut(20) formed with an internal angled surface(21). The angled surface of the gland is formed with a protrusion(26) to prevent the separation between the nut and the gland.
