HELP! 75 W115 300d - What does this do?

This just snapped off where it meets what I think is a control valve. Am I safe to duct tape it and drive to the shop? Thanks!

pic is kinda small for these old eyes... but looks like vacuum lie connected to intake manifold with check valve.
Hose broke at check.
Where does other end of hose go?
