Covering element for uncovered terminals of a switch which are operated by screws, in particular for line-safety breakers, which includes a bent part made of an insulating material, kept level with the head of the screw of the terminal and covering the uncovered portion of the terminal, characterised in that the bent part 6 made of an insulating material includes appended portions 6d in the form of plates, which grasp the screw head 5a laterally and, after being pushed perpendicularly to the direction of the axis of the terminal screw 5, are held there by automatic tightening, and is engaged, virtually without play, by a projection 6c made on the wing 6b of the bent part which is almost parallel to the terminal screw 5 and covers the outside 3b of a fixed pressure clamp 3, in an opening 3c in the pressure clamp, so that only an uncovered terminal housing 4 which has to be manoeuvred by way of the terminal screw 5 may move in the longitudinal direction. <IMAGE>
