ABSTRACT:
A quick connect and quick release coupling for connecting two pipes, including a male element and a female element that are axially fitted and interlocked one inside the other and wherein a locking mechanism retains the male element in a coupled position and a temporarily retaining mechanism immobilizes the male element, after its release by the locking mechanism, in a position for flushing a pipe connected to the male element. The locking mechanism is controlled by a sleeve that slides relative to a body of the female element. When the temporarily retaining mechanism retains the male element in flushing position, it is subjected to a first force (E1) derived from a pressure (P) of the fluid flowing (F) from the male element outwards and to a second force (E2), opposite to the first, exerted by elastic return means which, when the pressure (P) drops to a safety threshold, moves the temporarily retaining mechanism into a position for releasing the male element from the female element.
