The invention discloses a continued-connection of an external thread of a plastic pipe. The continued-connection comprises a pipe body. The continued-connection is characterized in that the surface of the pipe body is provided with a screw tooth opening, and the end part is provided with a taper-shaped screw tooth opening. The taper-shaped screw tooth opening can be connected with the plastic pipe spirally so as to prevent the plastic pipe from slipping; moreover, the male thread tee needs not binding. The male thread tee of the plastic pipe is simple in structure and convenient to use.
