An apparatus for capturing bottle necks in bottle filling installations includes a clip having clip arms. The clip arms are pivotable in a horizontal plane and mounted so as to be jointly pivotable in a horizontal plane about a pivot axis. The apparatus also includes an attachment for a magnet, and another magnet provided with the attachment and disposed on a side of the attachment such that the pivot axis is between the magnet and the clip arms, and a clip holding block configured to be secured onto a star and facing the clip and having a magnet. The magnet on the attachment and the magnet on the clip holding block are essentially opposite and spaced apart from each other by a distance that ensures horizontal pivoting movements of the clip.
