Sounds like you need a connector to the ventilation part of your unit, maybe the existing one is worn out, loose, or missing. Here is a link to Amazon, see if you can find your piece there:
Other than Amazon, contact the company who made the a/c unit, have make and model numbers ready so they can guide you.
To attach the venting hose to the AC unit, insert the vent hose into the hole on the back of the air conditioner unit and rotate counterclockwise to lock into place.
Have you tried a hose clamp? Cheap and easy to use. :)
You can purchase an adaptable hose clamp and clamp the two tightly together.
Mine came with hose clamps.
You can strap it on with a sturdy Velcro. Wrap tightly.
Hello might an adjustable hose clamp or duct tape help?
Hi Shelley: When all else fails, use duct tape :) It cures many problems for me :) Good luck
Hi Shelley, first check to see that you have it attached properly, there should not be problems with it coming off if correctly attached to the unit. If there is a broken tab or something, you can pick up a hose clamp at the hardware store and use that to attach it.
Hi there Shelley. If you know the make and model numbers of your ac, go to You Tube. They can provide a step-by-step tutorial for you. They have instructions on everything under the sun. We have used it a few times now, last time was a screw missing out of my ice maker. Good luck Shelley.
Maybe use a Jubilee clip or something similar........Best wishes!
Hi! I have one with two hoses, and I feel your pain! We were having trouble keeping ours attached until we went to the manufacturer website and found there was a simple way to tighten them. That's always a good place to start! Stay safe!
Could you use Duct tape to help keep the hose connected?
I would get a couple of those pipe clamps that have a screw you can tighten around the hose..... measure the diameter of the hose before you go to the hardware store.... https://www.truevalue.com/hose-clamp-5-16-7-8-in-4-pk
