Help! What Looks Like Some Heat Shield!

[red but not so fast!]

Starting my mondeo mk 3 tdci up to day i noticed a rattle! after getting out and looking under car i noticed that all the metal lining under the exhaust ( heat shield? ) had come away. it is severly hanging off and looks like it was held by bolts or rivets? any ideas if it can be held back on and do i really need it! thinking off getting ripped off but i cant get under the car anyway! is it dangerous if i leave it or even dangerous if i remove it? please help! it is this stuff in pic i am on about half way down the exhuast! :(
