A compound locking device has a casing, and a combination locking mechanism and a key locking mechanism disposed in different positions in the casing. The combination locking mechanism has a plurality of pairs of figure wheels and positioning cam sleeves. Each positioning cam sleeve has a limiting portion. All the limiting portions will form a large limiting groove if all figures are correct. The key locking mechanism has a lock body, a first bushing, a second bushing, and a tongue plate. The first bushing is linked with the lock body to be rotatable. The first and second bushings are connected together by means of wedge grafting. The first bushing is rotated to leave the second bushing for embedding the tongue plate into the large limiting groove. The lock body can thus drive the first bushing to rotate for unlocking the compound locking device.
