The old "breather hose" on my Mk3 VW Golf became cracked and fell off. I bought a replacement tube, which connects to part of the PCV apparatus on top of the engine via a hose clamp, but it is not clear how it is meant to attach at the bottom of the engine. There must be some kind of clip that I need -- how can I find the part number and order it?
Here is a photo of the engine compartment, with the tube in question outlined in red:
And here is a close-up of where it should connect to the engine at the bottom:
How should the tube be secured?
