Because I leaned my stand on the wall and constantly fell down the wings, I was looking for a solution.
The small clip is simply clipped to the attachment and holds the two wings firmly.
To make it easier to push in, I slightly rounded the back. This also results in a better strength of the clip.
Diameter is 12mm
