The utility model relates to a new composite pipe fitting spigot-and socket joint to connect metals of a water supply and sewerage system, an air feeding system, a chemical industry system and a heating power system and a plastic composite pipe. The present spigot-and socket joint is inconvenient to check the leak and has an insufficient connection strength and a poor spigot and socket effect. The new composite pipe fitting spigot-and socket joint comprises a plastic identity and a skin layer metal compounded on the plastic identity, and the spigot and socket connector is characterized in that at least one common end of the plastic identity and the surface of the skin layer metal is provided with a spigot and socket hole, and the plastic identity in this end extends out of the surface of the skin layer metal. The new composite pipe fitting spigot-and socket joint has a simple structure and is easy to carry out, and the new composite pipe fitting spigot-and socket joint can effectively solve the disadvantages of prior art and is suitable for various joints.
