I tried that method BUT the problem is that the ring is
"inside" the collector with no way to "get behind" the
band and "push" but I do understand what you saying.


Just push in the right spot. No need to un-do anything. Grab the bag with
your hand and push. A good push right below the housing will cause it to
pop inside and you just remove the bag. Honest, give it a try. Easy to go
back also.
