Female quick coupling and quick connector comprising said female quick coupling

A female coupling adapted to be connected to and disconnected from a corresponding male coupling by means of pushing and pulling actions, respectively, said female coupling and male coupling comprising a female valve assembly and a male valve assembly, respectively, each of said female and male valve assemblies being adapted to be alternatively translated forwards and backwards between a first closing position and a second opening position, wherein the flow of a fluid is possible between the female coupling and male coupling with said female and male valve assemblies in the respective opening positions, wherein said female coupling comprises mechanical locking means adapted to prevent the backward translation of the female valve assembly from its said second opening position, wherein said mechanical locking means comprise a rocker arm adapted to oscillate or pivot between a first engaging position and a second releasing position, wherein, said rocker arm, in its first engaging position, engages said female valve assembly, thus locking said female valve assembly in its second opening position so as to prevent the backward translation of said female valve assembly from its said second opening position, wherein said female coupling comprises a hollow main assembly, wherein said rocker arm is adapted to be translated with respect to said hollow main assembly between a first front position and second rear position, and wherein said rocker arm is adapted to be automatically switched from its engaging position to its second releasing position as the result of its translation from its first front position towards its second rear position.
