A connecting assembly for coolant lines, in particular for motor vehicle air conditioning systems which are operated with CO, from a first coupling element that can be connected to a first line end piece, and a further air conditioning circuit component. The first coupling element and the air conditioning circuit component are joined by a screw so that the first line end piece and the air conditioning circuit component are connected to one another by means of one bore each and radially extending sealing faces. A sealing ring is arranged between the faces. A space holder is arranged between the first coupling element and the further air conditioning circuit component. The first line end piece has a radially extending sealing face which is produced by plastic deformation of the line end piece without removing material. The first coupling element has an annular collar which presses the sealing face onto the sealing ring in the mounted state.
