Ducting Systems and Air Ventilation - Connecting dryer duct to another duct

I have two ducts in the house I'm staying in that are attached with duct tape. Problem is the heat and air dry up the glue on the tape and it comes apart. Is there an easy way to join these two. The local Fred Meyer was pretty useless in this regard. Thanks.

Retail duct tape should never be used for ducts. As you have found it is temporary at best. Are these metal ducts for heat and air or what. Are they covered with an insulation blanket? Are they just pressed end to end with no internal connector? Foil tape may work but with details we may be able to give you a better solution.

It's basically a metal like hose and a plastic type hose. I'd rather not replace the whole thing since I'm only renting and the landlord is in financial trouble, so his ability to fix it is limited. I'll only be here for another month or two.

The metal like hose has a round metal piece on the end. I'd tried bending it in a little so that it would go inside of the plastic. I bought some O metal things which tighten but they don't fit on either. I used the duct tape and taped it a lot to keep it shut. Or well, try to anyways. :)

So this is for a dryer. I missed that the first time. it's basically a metal like hose and a plastic type hose It is now illegal to use plastic ducting for dryers. Too many fires caused by them. Tell the landlord it is unsafe and needs to be replaced.

Ray,

Thanks. I'm not surprised. There weren't even smoke detectors in this house that were working when I moved in. It's like the cheap trick song. Here for a good time and not a long time. I'll probably just fix it myself for peace of mind and soon given that it is a fire hazard. I'll look online for any tips. Hopefully it isn't too difficult.

If you have any more questions post back. Ideally the dryer should be against an outside wall and vent directly outside. I get the impression from what you write that is not what your situation is.
