A pipe for connecting to a similar adjacent pipe. The pipe has a female end with a plurality of rigid fingers extending into the space within the female end. The plurality of rigid fingers extends from at least one interior circumferential groove on the interior surface of the female end. On the male end of the pipe there is at least one exterior circumferential groove that is sized and positioned to receive the plurality of rigid fingers from a corresponding interior circumferential groove on the female end of an adjacent pipe. The number of interior circumferential grooves on the female end with the plurality of rigid fingers extending from them typically corresponds to the number of exterior circumferential grooves on the male end. When the male end of a similar adjacent pipe is inserted into the female end of the pipe, the plurality of rigid fingers is received within the corresponding exterior circumferential groove on the male end, thereby preventing the male end of the similar adjacent pipe from being withdrawn from the female end of the pipe.
