Exhaust pipe is hanging off on 1990 Lexus ES250

The exhaust is hanging off, should there be a clamp holding the part on?

yes there should be a series of clamps. you can TEMPORARILY use a piece of coat hanger to secure the exhaust but then you need to have proper repair performed to your exhaust system ASAP because this is a safety hazard.
