ABSTRACT:
A lock intended, for example, for a door and comprising a lock bolt and a knob, handle or corresponding device (4) and an electrically actuable coupling arrangement (7, 8, 9) arranged through the agency of an electric signal to connect the knob to the lock bolt, so that the lock bolt can be moved to a lock-release position by rotating the knob, but which in an electrically non-activated position is disengaged so as to prevent the lock bolt from being manipulated by rotation of the knob.
