A battery housing (4) for a radio pager (1) comprises a slidable cover (5) movable between a first position, where it closes off an opening (3) for insertion and removal of a battery, and a second position where it leaves the opening accessible. The cover (5) is only allowed to move from its closed position when a slidable locking member (8) is moved to its unlocked position. Movement of the cover (5) from its closed position to its open position automatically causes the locking member (8) to be moved back to its locked position so that when the cover (5) is closed again, it is automatically locked in the closed position. |
