<p>A parking indicator for motor vehicles comprises a channel for the insertion of a value strip and time indicators which are not adjustable when the value strip has been inserted into the channel. In order to prevent the value strip from being withdrawn from the channel without being damaged, the value strip is provided with teeth mating with a toothed wheel arranged in the channel, the toothed wheel being rotatable only in the direction of insertion of the value strip, thus forming locking structure retaining the value strip.</p> |
