Bret ‘The Hitman’ Hart — Zie Germans Stole My Jacket!

Wrestling legend Bret Hart claims he was robbed blind in Deutschland Thursday — insisting his trademark shades and jacket vanished while he was in the ring … and the WWE suspects German foul play.

Sources connected to the wrestler tell TMZ … Hart removed his classic get-up before a match in Nuremberg — standard wrestling procedure — but when he got back to the locker room after the fight, his stuff hadn’t been returned … and no one knows where it went.

So far, no police report has been filed — but a rep for the WWE confirms that the jacket/glasses combo did go missing … and they’re convinced it wasn’t an inside job.

We’re told both WWE and the Nuremberg arena are desperately trying to track down the perp … who may or may not vaguely resemble the Fonz.
