PROBLEM TO BE SOLVED: To provide a pipe connector for a plastic greenhouse, capable of making the connection tight so that the screws of the junction of the pipe connector are not loosened by vibration or the like, and also making a bolt easily theadable through a bolt hole. SOLUTION: This structure of a junction of a pipe connector for a plastic greenhouse is such that a pipe connector 1 where one pipe holding body 2a and the other pipe holding body 2B are connected to each other using a bolt and a nut in a freely angle-adjustable fashion, has a recessed groove 7A concentrically circular with a bolt threading hole 6A provided on the periphery of the bolt threading hole on one side each of connective pieces 5A and 5B, and a projection 8A corresponding to the recessed groove 7A formed on the opposite surface of the connective piece 5A, and the recessed groove 7A of the connective pieces 5A and the projection 8A are engaged together through being superposed on each other.
