Abstract: The invention refers to a quick released system for coupling (1) and drogue (2) assembly comprises a crown coupling connector (4) suitable for being fixed to the coupling (1) and comprising cavities (14); a plurality of balls (3) housed in the cavities (14) with an emerging part and radially movable; a crown drogue connector (5) suitable for being fixed to the drogue (2), configured to engage and disengage the coupling connector (4) and comprising first recesses (26); and a crown locking ring (6) rotatable between a locked and a released position and comprising second recesses (31). The second recesses (31) are arranged in correspondence with the first recesses (26) when the system is in a released position and, the locking ring (6) in contact with the balls (3) and the first recesses (26) engaged with the emerging part of the balls (3) when the system is in a locked position.
