Sorry for the delayed response! :)
I am not sure what they call mine, but it IS a snap-on 2-piece system. The flange does have a plastic ring on it that snaps to the bag, like tupperware almost.
The product numbers for the items I use are:
flange:2832 (assura extended wear)
bag (the normal size): 13925
stoma cap: 2802
Hope this helps! I really like the system...the flange I listed works with both bags and the stoma caps also...
The bags and stoma cap I listed are all interchangeable with the flange I listed. When you call Coloplast (if you want to get free samples of these items), you can always ask the sales rep if a certain flange works with a certain bag--they are trained in this stuff and will know if you are ordering 2 products that will not work together.
