I believe you have two mounting screws for your air bag. They are accessed thru two holes on the back side of the steering wheel spokes. On my car the screws are torx (t30). A 2.5" torx bit is inserted into the holes to tighten the screws. I don't know if MB used torx in '95. It's sounds like one or both screws are loose. If you don't have tools, any mechanic should be able to tighten them for you.
