Locking device with a stator, a rotor, and an anti-pull-out device

A locking device comprising:

• a stator, a rotor,
• and
• an anti-pull-out device for preventing a key from being pulled out over a rotational angle range,
• wherein the anti-pull-out device is moved into a first position and into a second position,
• wherein the anti-pull-out device has an elastic design, wherein the elastic effect forces the anti-pull-out device into the second position,
• wherein the anti-pull-out device has a bent annular region for operatively connecting to the key, wherein the bent annular region comprises at least one gap in the first position for introducing a key,
• wherein in the second position of the anti-pull-out device, the gap is modified such that the key is prevented from being inserted or from being pulled out
• wherein when the key is rotated with the rotor of the locking device, the key assumes different rotational positions with respect to the stator and thus with respect to the anti-pull-out device, wherein in at least one rotational position, which corresponds to at least one start position, the key can be withdrawn, wherein in other rotational positions, which are designed as locking positions, the key is prevented from being withdrawn by the anti-pull-out device.
