An HF plug connector having an outside conductor part, and inside conductor part arranged within the outside conductor part and an end on the mating side that is designed for a plug-in connection to a complementary HF plug connector, wherein a housing made of an electrically insulating material, is arranged on the mating side end of the HF plug connector, at least partially surrounding the outside conductor part, wherein the housing exhibits a through-hole into which the outside conductor part engages. The outside conductor part has a first axial retaining element designed to a first predetermined section of the housing upon assembly on the outside conductor part and a second axial retaining element designed so that said second axial retaining element presses a second predetermined section of the housing together upon assembly on the outside conductor part.
