Child seat blocking seat belt locker

I assume I'm not the only one to hit this issue but I can't find a solution in the search function.

My children's car seats are fairly standard Britax high back boosters connected via ISOFIX. I've used these in numerous cars with no issues.

I've recently purchased a GLC and the seat is partially blocking the seat belt locking case. This is then exaggerated by how large the seat belt pin housing is. I hope that makes sense. I would need to bend the seat belt pin against the seat to angle it into the lock. I can manage to do this with force but my 6 and 8 year olds can't. I've considered getting seat belt extenders but they all seem cheap and nasty so not sure if they will fail.

Any help would be greatly appreciated.
