Abstract: Quick coupling including casing defining longitudinal axis, outlet and inlet, to receive at the inlet at least part of external connector to fluidity connect external connector and outlet, shutter housed within casing to translate along longitudinal axis in opposition to opposing element, housing at least part of external connector and including retainer to lock at least part of external connector within shutter in at least one position along longitudinal axis, controller accessible from outside and including first slider housed within casing to translate along locking direction skewed relative to longitudinal axis in opposition to second opposing element, to house at least part of the shutter and including lock to lock the shutter within first slider in position along locking direction, and safety to lock shutter when subjected to pressures above predetermined threshold by fluid present within coupling, wherein the shutter locks external connector at least when safety locks shutter.
