A cable tightening device includes a fixed unit, a rotation member rotatably mounted on the fixed unit, a movable unit including a movable member to drive the rotation member and a release member to lock or unlock the movable member, and a locking unit to lock the release member onto the movable member releasably. Thus, the release member is locked onto the movable member by the locking unit and cannot be pulled upwardly to detach the push plates of the movable unit from the ratchet wheels of the fixed unit so that the ratchet wheels are locked to lock the rotation member to prevent the cable from being loosened so as to protect the cargo wound by the cable, thereby achieving the anti-theft purpose.
