He has accepted responsibility, but wants me to file a claim and he will pay my deductible. Seems to me he is 100% responsible, and I don't want to have an insurance claim on my record for this.

It does him no good anyway since once the insurance company pays you, they will almost certainly come after him directly-- by paying you they are subrogated to your claim against him.
I would imagine the terms of your lease state what is to happen in the event he causes damage, and unless the lease says that you are compelled to do what he is asking for, you should be well within your rights to refuse his request.
You are under no obligation to submit an insurance claim.
