Patent ID: 8647148

Claim:
A connecting device for connecting a high-frequency (HF) cable to an HF Interface comprising: a connection part of the HF interface including at least one first groove in the axial direction; a sleeve formed at a first axial end for plugging together with the connection part of the HF interface, wherein a surface of the sleeve which faces the connection part of the HF interface in the plugged state of the sleeve includes at least one first groove in the axial direction; and at least one cylindrical pin engaging in at least one first groove of the sleeve and the connection part of the HF interface, such that the sleeve is formed, at a second end axially opposite the first end, for connecting to the HF cable, wherein at least one second groove is formed on a surface of the HF interface facing the sleeve, the arrangement of the cylindrical pin in two first and second grooves, which are aligned with one another, blocks a rotation of the sleeve relative to the connection part fixing the relative angular position of the sleeve relative to the connection part.
