A fluid system component is provided that includes first and second elements configured to be removably engaged with each other to define a fluid passageway. The first element defines at least one groove. Correspondingly, the second element includes at least one engagement member configured to be received in a corresponding groove. The presence of a line pressure in the passageway substantially forecloses disengagement of the first and second elements until the fluid pressure in the fluid passageway has decreased to a predetermined magnitude. A handling and locking mechanism for selectively securing the second element relative to the first element is included. The locking mechanism includes a pin controlled by a crank arm assembly adjacent a collar handle. The crank arm assembly includes a crank arm handle that rotates to withdraw the pin from the second element and which facilitates rotation of the first element relative to the second element.
