An RFI through-let for screening signals transmitted between different components, for instance circuit boards, of which one component is arranged in a screened space, includes signal-transmission through-let capacitors which are mounted in a screen plate intended to be positioned in a rectangular opening in the side-wall of the screened space. The screen plate is comprised of a front part which includes a rectangular, generally flat plate having tongues or tabs disposed along the sides thereof and also having a central, rectangular hollow, and a holding part which is soldered firmly in the vicinity of the hollow of the front part. The holding part includes a flat plate whose long sides are bent to form guide flanges which extend perpendicularly downwards away from the front part, along a first line corresponding to the long sides of the opening, and along a second line downwardly of the first line are further bent inwardly towards one another. Parts punched-out along the first line cause shoulders to be formed that project upwards and outwards towards the front part and are intended to grip-in behind the side-wall of the space when fitting the screen plate and therewith hold the screen plate firmly in the opening.
