1. Coaxial plug connector with snap lock for the communications technology, especially in motor vehicles, comprisinga plug with an outer conductor of the plug formed by a single-piece housing which, by means of a dielectric bushing, holds a plug inner conductor formed by a contact and behind the dielectric bushing has a rear section for gripping the sheath of a coaxial cable and in front of the dielectric bushing has a sleeve surrounding the contact in coaxial arrangement and on the outside carries a locking device, anda jack with an outer conductor and with a mating contact forming the inner conductor of the jack, surrounded in coaxial arrangement by the outer conductor and fixed in place by a dielectric bushing, and with locking means on the outside of the jack, wherebyupon completing the plug connection in the direction of the plug-in center line, the sleeve of the plug meshes with the outer conductor of the jack, and the locking device meshes with the locking means and, with respect to the inner conductor, contact and mating contact mesh with each other also, whereinthe locking device is a latching spring which is fixed at a location of the plug in the vicinity of the dielectric bushing and extends alongside the sleeve with at least one finger and at the tip of the fingers has a protrusion which is oriented toward the plug-in center line, whereinthe fingers extend backward from that location to form levers which can be pushed towards the rear section of the housing, causing the fingers to seing elastically outward, whereinthe locking means at the jack are formed by an outer protrusion or by a recess behind which or in which, respectively, the protrusions of the fingers can latch, and whereinthe latching spring has a ring by which it is fixed on the outside of the plug-in housing and from which extend the fingers as well as the levers for actuating the fingers.
