Air Duct to Air Box

[AlHeart]

I replaced the engine air filter and after reassembly, the air duct (4E0-129-627) between the inlet and the air box keeps popping off.

The part seems to be the original as the date stamp on it is 09/2002 and it isn't very flexible anymore. Are newer/new ones flexible enough that they would stay attached? Or does anyone have any tricks to getting it reattached?

I don't really want to buy one as it is an expensive piece of plastic! I can tape it up and call it a day if new ones will be similar.
