Abstract: A device for a coaxial connection that is intended to connect a coaxial cable (6) to the conductive pattern (3a) of a circuit board and contains an outer conductor (1) with an inner conductor (4) that is insulated relative thereto. The device contains a longitudinal coupling element (8) that is axially slidably mounted in a recess (4a) in the inner conductor (4;6a) and arranged so as to be in capacitive communication with the inner conductor (4;6a) and connected to the conductive pattern (3a). A layer (7) of insulating material is arranged between the coupling element (8) and the reccss (4a).
