The invention relates to a panic lock in which, when the key is withdrawn, a panic mechanism transmits the downward movement of the latch both to the catch and to the bolt in such a way that these can be drawn back. In order to ensure the possibility of actuation at all times independently of the beard position, a section of the two-part rear portion of the bolt (1) is caused to engage with the beard by means of the movement of the latch (7). <IMAGE>
