Abstract: A device for connecting a coaxial cable to first and second contacts which are secured in an enclosure. The enclosure is equipped with an insert having an inner bore to snugly seat the coaxial cable and whose center axis is in true alignment with the first contact. The second contact includes a contact spring device circumferentially clamped in the enclosure in an essentially rigid manner and having tabs with sharp free ends extending toward a contact pin rigidly fastened in the enclosure. The tabs are bent outward at identical angles from a plane defined by the clamped position of the contact spring device toward the inner bore of the insert. The insert is equipped with a rigid thrust face for exertion of pressure against the tabs of the contact spring device. The contact spring device, the contact pin and the insert are matched to one another and located in the enclosure.
