A theftproof clutch handle for a motorcycle includes a clutch connector provided with a plug, a handle body provided with a slot detachably mounted on the plug, and a locking device mounted on the handle body and releasably locked onto the plug. The handle body has a receiving chamber to receive the locking device. The locking device includes a support seat, a locking shaft, an elastic member and a drive member. Thus, when the drive member is pulled outwardly, the locking shaft is moved outwardly to detach from the locking hole of the plug to unlock the handle body from the clutch connector so that the handle body can be removed from the clutch connector to provide a theftproof effect.
