Abstract: A quick connector is described to removably connect hydraulic equipment operating in underground coal mines, wherein two tubular bodies are coupled to each other such as to define one individual fluid passage, a tubular element is movable between a closed position and an open position in which it either blocks or allows a relative axial movement between the tubular bodies, respectively, and a safety member slides on the tubular element between at least one safety position and a freedom position, wherein it either blocks or allows the tubular element to move to the open position, respectively.
