摘要：
A retaining device for a threaded connection that is expanded holds the connection together to prevent leakage. In a two step thread the retention device is located between the steps and comprises a nose in a groove that holds aligned surfaces together for a metal to metal connection and allows for relative axial movement at the same time.
