Abstract: A contact housing for coupling to a coaxial cable (1) comprises a housing (5) of electrically conducting material, which forms a connector for the screen (3) of the coaxial cable (1), and a therefrom insulated (7) coupler (6) for electrical coupling to the center conductor (2) of the coaxial cable (1). The contact housing can be coupled to coaxial cables of differing cross-sectional dimensions with minor modification. To this end, the center conductor coupler (6) of the contact housing (5) is formed to be capable of being brought into firmly retaining, electrical contact with the center conductor (2) of the coaxial cable (1). The center conductor coupler cooperates with a locking means (9) for locking the connection so established. The contact housing (5) has a locking sleeve (11) of electrically conducting material, and which can be connected firmly with the contact housing (5).
