A single-piece instantly detachable locking device for a bicycle carrier is composed of a base board, and a mobile hook installed at the base board. The top surface of base board is fastened to the bottom surface of the loaded piece, such as a traveling bag, basket or box, via screws or nails, while the bottom surface of the base board leans against the top surface of the bicycle carrier. More than one fixed hook are downwardly provided at one side of the base board, whereas a mobile hook is provided at the other side, such that the aforesaid hooks can be combined to the two sides of the bicycle carrier and locked to the bottom side thereof. Accordingly, the locking device can allow a loaded piece be easily fastened to the bicycle carrier, and can be instantly detached when it is not in use.
