For years now I've had 400' of garden hoses going from well to water tank. Finally getting around to replacing it with 1" black poly tubing. The barbed fittings, how are you supposed to attach them? Won't go in cold, I heated the tubing until soft enough to push then fitting in, now it's loose. Do they need a clamp? Not under pressure, just fills the tank.
After that I just have to figure out what to do with 8 garden hoses.

Did you have any lubrication on them when cold? I think ideally the install would be a nice tight pressure fit (unheated) w/ lubrication (a small amount of dish soap or cheap food oil works well.) And then you can throw on a hose clamp for good measure when done. I think you will have leaks into the future if you hose clamp it while loose now.

If you're having trouble getting the fitting in you could try tapping them in with a rubber mallet and something to protect the end of the barb you're tapping. A tight fit is a positive thing in this instance.
A good barbed fitting connection usually requires about 4 bad words outta me before seated properly. That's how you know its good

I used Ford compression fittings. However, they are expensive. Here is a video on doing poly pipe with barb fitting:

Thanks guys. I pulled the loose one off, cut the hose and was able to knock it back in cold with a rubber mallet. Didn't ever cuss once. Going to put hose clamps on like the video.

I had a friend gift me a jar of a slickum used in the automatic transmission rebuild shop; no idea of the name, back in the mid-70's. Iirc it was a special 'seal-goop' but he told me it was good for lots of things.
Ive used it on hard to get together fitting, works well, bet it would have done this job.
Ive even used it on seals, lol.
Btw, a little goes a long way.

One drop of DISH SOAP on the barbs make it slide in and is SAFE (ie not toxic & cannot harm the poly). This is your "potable" source right ? Think on that, please.

You may be thinking of Assembly Goo, I have a tub of it, lasts a lifetime. Great for holding parts in place while fitting things together, and dissolves in use.
I was able to tap the fittings in today dry, I don't know what I was doing wrong last week, at least on this project. 
I did fill the water tank, it fills a lot faster with the 1" poly than the 5/8" hose.

We use poly pipe almost exclusively at work for our irrigation systems. A two second shot with a small torch softens the pipe just enough to insert the fitting, then install a clamp. If you are using thick wall poly you might need to heat it a second or two longer

I'm going to finish this project today I hope. Funny, only 4 ends to deal with and I have been to hardware stores several times. Much less 1" fittings than 3/4. I debated what size to use (400' run from well to tank, uphill), 3/4 probably would have been fine. It's pretty thick wall but the last fitting I put on went in cold just with a rubber mallet. And I'm using regular worm gear hose clamps, I guess that's the norm.

I use crimp clamps on most fittings but they can be hard to find in some areas

Funny story. Yesterday I filled the water tank through the new 1" poly pipe. So as usual, I fired up the dedicated 220v generator in the well shack, drive up to the cabin, then hike up to the tank to make sure water is flowing into it. All good, but as I'm doing a few things around the water tank, flow stops. Argh. Hike down to the ATV, drive down to the well shack thinking maybe the well is dry and the expensive well pump is running dry. Nope, the fitting at the shack to the new pipe came apart, Hadn't put a clamp on it, just pumping water onto the dirt. So I shut it down, add a clamp, fire it up, drive/hike back up the water tank, continue cleaning up there. Flow stops again a minute later! This time I can't hear the generator, the 10 horse Tecumseh is loud enough to hear at the cabin. Hike/drive back down, starts first pull. Hmm, just a hiccup I guess. Drive/hike back up. Soon as I get to the tank, it stops again! GRRR. Hike/drive back down, pull the start rope, it breaks. Pull that off and fix it, fires right up. Pull the float bowl off, clean inside, jet clear. Fire it up, back up to the tank, dies again! Got to be fuel, it's not seizing, has good spark, starts right back up. FINALLY, I look in the gas tank with a light, there is a piece of crap sitting right at the outlet. No stand pipe, just a hole at the bottom where the line connects. So I got that out of there with some grabbers, all good. I guess every time it died and the suction stopped the debris would move out of the way. All good now, tank fills at least twice as fast with the new pipe. I was beat after all that, and it got pretty hot out, so that was about it for the day.

Glad to hear your burned your calories for the day 
But boy oh boy I know how frustrating those kind of projects can be! Sounds like a typical cabin project for me - loving and hating every minute of it
