A device for earthing a bundle of shielded cables as protection against high frequency electromagnetic interference includes a rectangular metal collar in electrically conductive contact with the equipment to which or from which the shielded cables run. The cable shields are exposed and pressed into contact with an electrically conductive base plate in electrical contact with the collar, which includes pair-forming openings in each of two mutually opposing sides. The base plate is provided with pairs of outwardly projecting fingers intended for insertion into some of the pair-forming openings. A spring unit, including a pressure plate, a spring, a locking plate provided with pairs of outwardly projecting fingers, a counter-pressure plate, and a holder device, is intended to be inserted in pair-forming openings at a distance from the base plate via the fingers on the locking plate. Before installing the cables, the spring is mounted in a substantially compressed state between the pressure plate and the counter-pressure plate with the aid of the holder device. After installation, the holder device is loosened so the spring extends and applies a constant pressure to the cables installed between the base plate and the locking plate.
