air suction valve hose is off / loose

The more I fix things on my bike, the more things I find to fix.

I was taking off the gas tank while removing / draining my radiator, and I noticed one of the two tubes that come off the front of my air cleaner housing was off / loose. Looked around at some fiche and saw that it's the tube that goes to the air suction valve (it's the tube on the left, if you're looking at it from the back of the bike). Seems like there used to be something that it would clip on to to stay in place which is no longer there.

The hose itself connects to the air cleaner housing into a separate 90 degree plastic piece. Since I can just remove the hose / clip if I need to separate it to remove the air cleaner housing, can I just glue the 90 degree plastic piece to the housing? If so, do I need to worry about heat, or use any special adhesive? Other ideas on how to make this tube stay in place.

I can post some pictures if that'll help.

From the previous thread, the fan was definitely dead, which is why all of this came off.

As always, thanks for the advice.
