A locking apparatus for a folding top of a vehicle includes a housing, a locking hook having a gripping end and a bearing end, a coupling device, and a driving apparatus. The coupling device is movably mounted in the housing to be horizontally adjustable in a longitudinal direction of the locking hook. The bearing end is pivotably mounted to the coupling device around a pivot axis oriented horizontally perpendicular to the longitudinal direction of the locking hook such that the locking hook is horizontally adjustable in the longitudinal direction of the locking hook between closed and opened positions. The driving apparatus is connected with the bearing end through the coupling device for driving the locking hook to move between the closed and opened positions.
