摘要： A screw connection device for fluid lines, in particular for motor vehicle fluid lines, having a coupling nut with an interior space and having an internal threading running over the circumference of the interior space, as well as having a connecting element with an external threading. A line end of a fluid line is accommodated in the coupling nut, wherein the line end exhibits an end shape. When the internal threading of the coupling nut is screwed to the external threading of the connecting element, a locating surface disposed in the interior space of the coupling nut is moved toward the back end of the end shape, or vice versa, respectively. A spring element is disposed between the locating surface and the back end of the end shape, running over the circumference of the fluid line.
