A mobile telephone battery cover locking mechanism includes at least one latching member and at least one spring loaded locking member adapted to securely engage the latching member at one end when the latching member is fully inserted in at least one spacing provided at that end. The latching member forces the spring loaded locking member to move against its spring bias when the latching member is being inserted in the spacing with the spring loaded locking member having moved under its spring bias when the latching member is fully inserted in the spacing. The spring loaded locking member may be moved against its spring bias to allow the fully inserted latching member to disengage from the spring loaded locking member.
