There is a clip. Gray in color. Broke mine a long time ago. Hose stays in place without the clip.

 

Ok, I'll have to take another look to see how the clip comes off.

 

I think you have to squeeze it so it clears the lip on the metal flange part. It's been so long.... I broke it years ago

 

Do you also need to remove the resonator?

I messed around trying to figure out how to separate the hose from the throttle body and completely struck out. I can't get in there to get at the clip, let alone tell how to unclip it.

 

The only time I've ever needed to get that hose off is to remove the throttle body to clean it, so I've always had all the breather parts already off. If I remember correctly, you just press down on the plastic piece on the hose so it clears the "lip" on the tube and it slips right off. Here's a video, it's about 3/4 of the way through the video. Hope this helps:

This will hopefully help you to remove the gas line clips and the electrical connection clips for the Chevy Colorado and Gmc Canyon...

 

I broke that vaccum line the other day. I bought the replacement but can’t figure out where the other end of it goes, or how to take it off. Any ideas?
