Abstract
The two end members (1, 4) are locked by a self-retractable hook (15) which engages in a groove (23) in the female end member (1). The hook (15) is connected to an actuating lever (11) biased by a spring (14) and provided with a push-button (20). Pivotally mounted on the other arm of the lever (11) is a yoke (6) mounted on the male end member (4). When the transfer has finished, the hook (15) is retracted by depressing the button (20) so as to unlock the coupling. In the event of frosting, by depressing the button (20) still further, the yoke (6) upwardly urges the female member (1) and separates the two end members. Application in the transfer of liquid oxygen from a storage container to a portable container for domestic oxygen treatment.
