Bathroom fan/ducting attachment question

I have a inline Fantech 100CFM fan that was replaced upon my request when purchasing my home. When i went into the attach I noticed they never attached the top ducting to the fan.

It is 4" flexible duct.

What do professionals use to attach the 4" duct to the 4" exhaust on this fan? Is it tape, what kind of tape. Or is it a band clamp with tape? What do all your professionals do? The other ones in my attic are just covered in with duct tape? However it all seems sloppy and definitely unprofessional.

Tape with silver tape or heat activated tape then band together.

I tape it with foil based HVAC tape then put a hose clamp on top.

What kind of foil tape do you recommend? I already have 3M Foil Tape 3381. This is just the thin 1.4 mil strength cheap 3M tape I used to rewrap all my geothermal in.
