Can anyone recommend a rear bike basket WITTHOUT quick release that is compatible with the bontrager bike rack?

I commute and have a trunk bag, but I have to wear a suit to work, so I can't take it off and place it in the bag without getting wrinkled. I'd like to switch to a bike basket, so I can just fold the jacket and place it inside. Here is the kicker - I'd like a basket that can not just be slid off, which will allow me to park it at the train station.

Any suggestions?
