Identify these hatches/windows?

We have several of these (as below) on the boat, I guess they are plastimo,but not sure. Boat is a Dufour 405
The seals are substantial, and the clip robust but most leak a small amount of water which is a pain.

Adjustment doesn't seem possible, so guess it's new seals?
Any thoughts/advice/or gentle abuse welcome

Thanks
