I can't leave mine on permanently only bc I use a heated water hose in the winter and that has to be directly screwed on.
BUT, I can exchange other hoses during the growing season and leave the piece on for that.
They were all the rage about 3 years ago, now, not so much.
@Finnie you might want to buy this, instead:
Buy FUNJEE 304 Stainless Steel Metal Garden Hose with Solid Brass Fittings, Heavy Duty Water Hose, Kink Free and Flexible, Crush Resistant, Puncture Resistant (stainless steel hose, 5FT) at Walmart.com
www.walmart.com
This wasn't available until, I THINK, this year. It comes in 3 lengths.
My problem with my heated hose is that the electrics heat up water a couple of inches down from the faucet/water source. Too much unheated hose distance and I get ice.
I have 2 heated hoses and they work efficiently until it gets to about 5 degrees F with a stiff wind, and then it cannot move warm water 100 ft to where I need it. Then, I have to fill buckets in the basement, carry them up 5 1/2 steps and through a landing, over the back door entrance and to a 40 gallon portable water trough.
It is quite the workout.
With my new left knee I should not have too much trouble with this, since I have done it even last year while I was healing up the right knee.
My heated hose(s) has/have a plug, which I connect to an outdoor receptacle with an extension cord, and I run the connection through a cover, Like this one:
This affordable Twist and Seal Cord Protect Outdoor Extension Cord Cover and Plug Protection Green allows you to mount your tv with multiple turns and bends, without buying another complete kit.

I have one of these are several of the orange, rounder and smaller versions so that my electric hose connections don't short out.
I have one faucet for incoming city water and another pulls water from one of my cisterns, and the pump is in the basement.
I have been filling up the horse tank with this one bc our city water is becoming heavy with chlorine.
When I want to top off the 10 gallon fish tank, I take tap water, which runs through our whole house filter, then fill a 2 gallon pitcher of the water I filter for drinking, and then I let it sit for a day to let any chlorine evaporate.
This has worked well and we know that goldfish are very sensitive to water contaminants.
I here gardeners suggesting that we try to use rainwater for growing now instead of city water for the same reasons.
I have a project to attach the rain barrel that I have in it's box in the garage to the downspout SE side of house, and then attach a 50 ft hose to that and let any water spill into the cistern.
