The radio telephone also comprises guide means for guiding the relative sliding movement, the guide means comprising a guide track on the cover (2) and a guide rail on the body (3). The guide rail extends along a portion of the guide track when the cover irrespective of the relative positions of the cover (2) and body (3) and the force between the cover (2) and body (3) is substantially constant over a range of positions along the guide track, which leads to a tactile improvement for the user.
