Safty Flag Clip for child transporter

These are two Clips to add a Safty Flag on an old child transporter.
In my case it is a burley with 22 mm aluminium tube frame.
The Diameter of the bigger hole is 22 mm and the small one is for a 6 mm flagstuff.
I use stainless socket screw (M4 x 16) with self locking nut.
