Canister line

I am going to replace the charcoal canister on my 2002 Tacoma Reg Cab with 83000 miles , I have had a 441 - 446 code and have NC emissions test coming up. I was looking at my plan of attack before I get the time to install new one , and I am not sure how to remove the hose connection below with arrow .... I do not want to break it , and it needs to be able to be used on new canister. Is there a certain way to unclip it . it does not want to spin .....

The Hose nubs top and bottom are portion a in step D2. Simply pinch the hose top and bottom and it should pull back. See the rectangle portion top and bottom with the protruding part, I think when you pinch the section between the rectangle part and the end of the clip it will release. I have a 442 code but damned i can track it down.
