Does the wall termination vent for a kitchen range hood need fastened to the duct tightly?

6" duct running out through exterior wall. For my dryer wall vent, I used a pipe clamp to tightly secure the round duct around the outside of the male fitting on the wall vent. I have access to this space if I ever need to replace the wall vent. Once this kitchen is done, I will not have access to the space for the range hood vent. Looking to the future, in case I ever need to replace the wall vent, do I simply friction fit the male fitting of the wall vent into the range hood duct so that I can easily slide a new one in?

I can’t see any way people could replace these in an exterior wall if they secured the duct to the vent with a clamp or tape.
