ABSTRACT:
A rapid coupling system for establishing a connection of at least two pressurized lines in a pressure sealed manner is provided. A first coupling plug element has an operating mechanism, including a journal, in a connecting block thereof. A second coupling socket element is adapted to be connected to the first coupling element in a pressure sealed manner. A control unit is arranged in a socket element connecting block and includes a displaceable plunger having at least one cam. A pressure relief unit is connectable to at least one of the pressure lines via a pressure relief connection. When the first and second coupling elements are connected to one another, the journal of the operating mechanism displaces the control plunger, causing at least one cam of the control plunger to engage the pressure relief unit.
