More ingenious designed clips.
This time on a diesel heater pump

What are they called. Opened easily


Now I cannot close them.
I can't stop them spinning around the pipe as I try to clip them shut. What's the trick?

How do you do them up?

I'd swap them for the screw type ones, like you have on the other pipes. They are not really designed to be reused, but a pair of Olde Worlde pinchers will do them up. Might get away with using a pair of side cutters.
 
I guess if you're fitting a lot of hose clips on a factory production line there maybe a benefit.in fitting hose clamps that clip shut with a special tool.

But in an awkward space on a boat, just the wrong.thing.

Got my new ones and fitted them today. Took a couple of minutes. Easy.

Jury rigged an exhaust so I could test the heater and it works. Happy days

Now to sort out wiring routing, the exhaust, and hot air ducting.

Pincers make closing easy
As you found, they're easy to remove and don't have the problems of screw hoseclips.
 
Yes, so would I. Much better than the "jubilee" clip on small diameters, and easy to find in the days of Ebay etc.
The smallest size that a conventional worm drive hose clip will screw down to is 9mm. Do not be tempted by the fact that Jubilee now coin the band all the way around into thinking that you can just do it up further - the housing design only supports a min of 9mm before you start getting gaps under the band at the edges of the housings and then leak paths. Better, I think, to buy a brand that only coins the band in the part of the band that the clip can actually be tightened to.

A lot of fuel lines etc are smaller than 9mm so another solution is needed.

I can't make out in the OP exactly the type of clip, but a lot of places use "ear" clips. For example, Double Ear Hose Clamp - 3.1-4.3mm - Zinc Plated.
These need a special tool to be installed and are single use. The automotive industry use them in the millions.

The "mini clip" type are probably the best option for DIY use on smaller hoses, but be very careful with what you source, especially if buying from ebay etc. Some advertise as stainless but the screw, and/or the little captive flat nut aren't. And never, ever be tempted to "make do" with a mini clip that isn't quite the right size. Especially on a gas pipe. They need to be correctly sized to get a good seal. If the clip is too big you can sometimes deform them with excessive input force so that they will grip the pipe and you think they've sealed, but you've created leak paths in deforming them. Similar if you open one up too much, it might "do up" but if you haven't got band pressing on the entire diameter you have got a leak path.

Once you are over 10mm though, no solution offers better sealing than a worm drive hose clip.
