A cold and hot water connecting tube structure for plastic faucets comprises a connector and an inlet duct. The connector includes a tubular portion and a larger-diameter stop flange with a smaller-diameter threaded tube integrally molded to protrude downwards at the other end. The threaded tube has a watertight ring mounted to an annular groove defining an appropriate position thereon to for m a set of abutment flanges at both sides. The inlet duct has an oblique guide slope cut at one end edge to abut tight against a water-sealing ring mounted inside a locking head of a cold/hot water pipe, and a conjoining section with an internal-threaded section defining the internal surface of the other end. Therefore, the connecting tu be can be accurately joined without any chinks caused by cold-contraction to ensure secure connection thereby. And the separate-type design thereof also permits easy assembly and replacement of the present invention.
