In this embodiment, the connector 1 and the annular connecting part 4 are integrally formed, which can effectively improve the structural strength. The cross-section of the annular connecting part 4 is "L" shaped. The connector 1 and the annular connecting part 4 cooperate to form a positioning groove 6, which is annular.
[0027] The outer wall of the corrugated pipe 2 is provided with several buckles 3, and the side wall of the annular connecting part 4 is provided with several connecting holes 5. When the end of the corrugated pipe 2 is inserted into the positioning groove 6, the outer wall of the corrugated pipe 2 abuts against the inner wall of the annular connecting part 4, thereby forming a stable contact surface. Moreover, the several buckles 3 are respectively engaged with the several connecting holes 5. The buckles 3 are engaged with the connecting holes 5 to prevent the corrugated pipe 2 from falling off or loosening, thereby ensuring the stability and reliability of the connection.
