Water pipe connector

The invention discloses a water pipe connector. According to the water pipe connector, the inclined faces of locking sleeves and locking rings are made to slide through two locking mechanisms which are arranged oppositely and through threads so as to enable hoses at the two ends to conduct expanding and compressing. The pressure resistance of expansion-type fastening connection is stronger than that of clamping hoop compression-type fastening connection. Moreover, due to the fact that materials of the hoses are used for sealing, the leakproofness is better.
