Hiya Bug,
Take a look at the following.............
The elbow you need is listed as #1 in this diagram. #71 is the connecting hose (same size and type as the hose shown in your picture) up to the air cleaner horn and #72 is a rubber seal which sits on the rear engine tin (not shown in this diagram) to seal the engine compartment.
The elbow is bolted in place via two attachment points - one bolts to an exhaust flange , the other to the rear engine tin. The elbow itself has an asbestos jacket.
These elbows are not all that difficult to locate in a VW oriented boneyard. If you do not have such a salvage facility close to you, try online shopping at Way Out Salvage
