The latching lever, which comprises two arms arranged in the form of an L can pivot into a latching position about a pivot which is arranged on said side wall parallel to the pivot of the front cover. The longer arm of the lever is elastically deflexible over at least a part of its length and at one end comprises a latching portion which during the pivotal movement of the lever is guided by guide means disposed near the latching portion. The shorter arm is connected at one end to the pivot of the latching lever.
