Disclosed herein is an end connector for fluid communication with a valve. The end connector includes a fitting body and a lock ring for engagement and disengagement therewith. A nut is provided for securing the fitting body to the valve, and hook and chain assembly is provided for securing an eyehole of the lock ring to an end fitting, such as a cap, which is received at an end of the connector opposite the valve. In some aspects, the fitting body includes radially extending lugs, and the lock ring includes radially extending notches corresponding to the lugs. The lock ring, in a first rotational position, is configured to abut against the lugs to inhibit inadvertent removal of the lock ring. The lock ring, in a second rotational position, is configured to have the lugs in alignment with the notches, such that the lock ring can be removed.
