How to remove connectors from bulkhead

I make tools for that out if the little stainless steel strip in old windshield wiper blades. Swapping fuse blocks is prominent in collision repair.

Thank you everyone for your suggestions, will make that tool , although, I have broke that tang off (my Bad), and still can't get it to move, more patience.
We have the best members here, without their help I would be lost.
