That pipe is part of the crankcase ventilation system (PCV). If its broken you need to replace it.

I believe this pipe is hard plastic on older engines and was replaced with a rubber one.

To replace you will need to remove the top intake manifold (same as if accessing spark plugs) as the pipe connects at the top of the engine.

To remove the bottom hose clamp could probably get away with just removing the oil filter cover (36mm socket) to gain enough access to remove the hose clamp.
