Does anyone know what kind of blinds these are (and how to fix them)?

Hey all, I recently moved into a new flat that has these blinds I haven't seen before:

They seem to be fixed into the PVC somehow and I can't seem to locate any screws. On the inner side there seems to be some kind of metal fixing:

The issue is, one of them is ripped, so I'm trying to remove it to fix it. Does anyone have any idea how they can be (safely) removed? If not, does anyone know what this type of blind is called so I can at least try to find it on YouTube.

Perfect fit blinds, the fixings will be on both sides about a credit card size up and down in the rubber seal, just push the little metal bit you see in the hole, and pull blinds out, you can buy replacements online ie Blinds to go.

Had another look, yours look slightly different, could be a different/older type, have a look at INTU blinds.
