A fan duct is retained on a fan. The fan has an outer frame. The outer frame forms a plurality of cavities in an outer circumferential surface thereof. The fan duct has a main duct wall and a connecting wall. The main duct wall has a fan-end opening. The connecting wall extends outwardly from the fan-end opening of the main duct wall and has at least two hooks. An edge of the outer circumferential surface of the outer frame of the fan matches an inside of the connecting wall, and each of the hooks locks into a corresponding one of the cavities. As a result, the fan duct of the present invention is capable of being easily hung onto the fan, so that the fan duct can be mounted on and detached from the fan without requiring the use of tools.
