When the holding element is in the holding position, it protrudes into the latching opening. As a result, the holding element holds the latching head in the latching opening and prevents the latching head from being moved out of the latching opening. When the holding element is in the release position, the holding element releases the latching opening. In the release position, the holding element thus enables the latching head to be moved out of the latching opening.
