The tool for tightening the cotter pin types consists of a partially flattened tube with a t-handle welded to one end. I had one when I worked in a Fiat dealership, many moons ago. The hex-headed ones used on the 750 cars are much nicer, IMHO, not least of all because they can be tightened with a normal socket.

The only drawback of these clamps, for our Giuliettas, is that they should not be reused, though the pin and clasp can be recycled for use with fresh banding.

I found a couple of photo's of original clamps in situ and it appears that it isn't necessary to wind the band around twice. Once should suffice, although twice probably helps seal a bit better!

Thanks for the info on the special tool. The end of an allen key through the eye works fine though.

Tim, I can't cite any SAE studies for you, but I think that the double loop is important to a secure connection with a Copiglia style clamp.

Thanks Tom. Here is a pic of an original installation on an air hose.

However, that's an air hose where the sealing isn't quite so critical. I agree that 2 turns would be better, and also helps the strap to tighten evenly around the circumference. I'd go for that on the water and fuel hoses.

Here are a couple of original clamps from my car - one for water and one for fuel. Both are double looped.

For air, you're right - not so critical.

This is an old thread with some good information.

One day I noticed that the open end of one cotter pin from a Copiglia hose clamp set exactly fit in the loop end of another cotter pin. One cotter pin works well to tighten another although you can apply more torque with a longer tool, like a small screw driver. Also, the banding material from a larger hose clamp can be reused on a smaller hose clamp connection, if the coiled end is removed.

I have found that original connections that hold a liquid (coolant or fuel) should have the flat wire 'doubled up', while air ducts only need one loop of flat wire.

I know a clamp is missing, but here is a photo of a fairly recent installation. Fran

First time I used copiglia clamps, I was certain they would leak...they didn't.

Plus, they just look cool.

Copiglia hex type clamps

Tim,

Reviving this thread...

What width band should be used for fuel lines? Would a double-banded 9 mm not work, if a more narrow band could not be found?

Any source for the hex head portion of the clamps?

VabeneGTV,

Do you know of a source for 5 mm width band?

Thanks,

I buy 5 mm width hex headed Copiglia clamps from Scott Gray. I do not know where you can buy the cotter key fasteners, but I think that you can use a cotter key and cut it too length.

Restoration Supply Company has both the strapping and the ends in 5 mm and 10 mm sizes.
