A locking device for a top of a convertible vehicle is proposed, comprising a locking support (22), a locking hook (28), which can be shifted in a translational and rotational manner so as to be displaced between a release position and a locked position, and a driving mechanism for the locking hook (28), said driving mechanism comprising a driving motor (64) and driving a slide (36) movable on the locking support (22). The slide (36) is connected to a driving section of the locking hook (28) via a pull-link arrangement (46) in such a manner that the locking hook (28) undergoes a pivoting movement when the slide (36) is moved. The locking support (22) has an insert having a guiding track for a guiding element which is arranged on the pull-link arrangement (46) or on the locking hook (28), and the guiding track defines a pivot position of the locking hook (28) with respect to the locking support (22).
