I have tried using a battery of Mikalor heavy duty clips along the entire length boiling the horn and then tightening the clips. This works a treat initially and really pulls the horn in quite easily…. However when you reach a certain point and the torque increases the threads just strip on the clips.
How elastic is the material? How quickly does it spring back when a clamp is released?
The Mikalor clips have a range over which they are designed to clamp. Exceeding this will, as you have found out, lead to breakage. Once you reach the lower limit of a particular clamp, you might have to release it and replace with a smaller one.
One principle of the piston ring clamp that you might borrow is the spiral of spring steel that surrounds the rings. If you put something similar on the horn, and then the Mikalor clamp over it, the spring steel should slide over itself, especially if lubricated, and reduce the force needed.
