Just how do you regard having your duct joints fall apart as desirable?
Seems to be a bit of a disaster to me.

If ducts are made properly, they should be locked together by a folded
seam by which the ends of the ducts slide together and an edge is then
folded over to lock it all together.
Look up "pittsburgh seam" or "pittsburgh seaming" and "ducting" on Google.
