The invention provides a locking device for a derailleur and the derailleur. The locking device is arranged on a movable component of the derailleur and can be connected to a chain guide piece of the derailleur, the locking device comprises a driving unit and a clutch unit, and the driving unit is arranged to receive an electric signal and drive the clutch unit to be switched between a connection state and a separation state through a motor; wherein, in the coupled state, the clutch unit couples the chain guide to provide resistance when the chain guide is rotated in at least one rotational direction with respect to the movable member; in the separation state, the clutch unit is disconnected from the chain guide so as to remove the resistance; when the derailleur is in the gear shifting process, the clutch unit is in the separation state. The locking device for the derailleur and the derailleur are used for solving the problem that the derailleur is large in damping force in the gear shifting process.
