Clamp for oval fork?

Hi

To attach this part [1] on the front fork with an oval cross-section, I need a clamp like this but with an oval shape, knowing that the fork’s larger diameter is 3 cm and the smaller diameter is 1.5 cm.

[1] It’s part of a magnetic locking clip. This keeps a folding bike in the folded position.

Thanks

I already managed to attach the other part to the rear stay.

Well, in the end, with two clamps like the one above, I made an oval clamp.

And here’s the result.



I now have a magnetic clip to lock the bike’s folded mode.
