The invention relates to a device for fire retardation for electrical cables (2) in wall bushings, ceiling bushings or similar bushings. The electrical cables (2) as well as fire-retardant sealing or insulating material (5) which is flexible and surrounds these cables are fixed in a housing (4), which is open at its ends (4a, 4b) and is in the form of a channel, with the aid of a slide (6), so that, if necessary, subsequent changes in the installation of the electrical cables can be carried out quickly and without any complications, the fire retardation being produced again simply by pushing the slide in again after the installation. <IMAGE>
