Abstract

A coupling for use in a fluid flow line. The coupling includes first and second parts (12, 14; 112, 114), and the coupling has a first condition in which the first and second parts are connected to one another to define a fluid flow path, and a second condition in which the first and second parts are disconnected from one another. The coupling includes a sleeve (16; 116) configured to secure the first and second parts in relation to one another. When the coupling is in the first condition, the sleeve is movable between an open position in which the coupling is able to transition from the first condition to the second condition, and a closed position in which transition of the coupling from the first condition to the second condition is prevented. The coupling further includes a blocking mechanism (18; 118) for preventing movement of the sleeve, when the sleeve is in the open position. The coupling is configured to activate the blocking mechanism, during transition of the coupling from the first condition to the second condition, to prevent movement of the sleeve from the open position to the closed position.
