Quick acting coupling for the disconnectable connection of two pipelines

The invention relates to a detachable joint the fast connector for two fitting, comprising a suitable for interlocking an inserting part and a principal axis direction and is matched splicing part; and connected to the inserting part comprises at least one admitting for inserting part of the slopeway a radial bearing; the connector is at the connecting position of the locking component. The slopeway formed, or is fixed on for receiving the two ends of the ring is part, the capable of freely rotating; and along the axial direction of the moving fixed; The retractable to the embedding part is fixed; the slopeway of the when the connector is at the connecting position of the retractable the first support and when the locating pipe is provided with a pressure releasing state lock to the retractable the second support, wherein the opening and significance the second support is corresponding to the first support axial biasing. The connection part axially moving actually, capable of a locking.
