A closing device for a lock, comprising a pivoting bolt that can be closed in a forward and retracted position with the aid of a locking means. The invented device also comprises a closing element (13) that accommodates the bolt in a forward close position and a locking and unlocking device for said bolt. The locking and unlocking device comprises at least one locking element (17, 18) that can be moved forwards into the movement area of the bolt or retracted, whereby the pivoting bolt is secured in a forward position against closure in a retracted position or retracting from the forward close position. When in a locked position, mechanical door-side interventions on the locking mechanism of the locking cylinder or the pivoting bolt-lock do not result in a closing movement of said bolt.
