摘要： The invention relates to a plug-in connection system (1) for fluid-conducting components, in particular for fluid-conducting components of fire extinguishing systems, comprising a first component (3) having an outer peripheral surface (7) and a first recess (11) in the peripheral surface, a second component (5) having an inner peripheral surface (7) and a second recess in the inner peripheral surface, wherein the first and the second component (3, 5) can be plugged into one another such that when they are fully plugged into one another the recesses (11, 13) lie opposite one another and define a locking element channel (14), and a locking element (15) which, when the components (3, 5) are fully plugged into one another, can be inserted into the locking element channel (14) until an interlock position is reached and at least part of which engages in both recesses (11, 13) in the interlock position.According to the invention, it is proposed that the plug-in connection system has a locking element safety device (20) for reversibly releasably securing the locking element (15) on the first and/or second component (3, 5).
