Mine has
circlips. I have taken these off and [...]
I normally have a devil of a job gettign
them off without them flying
across the room....
If they're the kind I think you people mean, I know someone who calls
them "jesus clips" because, as he described it, you try to take one off
and struggle and eventually it comes free - and goes *ping!* across the
room and you go "jeeesus!!".
That sounds like them. I've seen them called 'E clips' too, due to the
chape being somehat similar to a capital 'E' with cured top and bottom
and a very short middle bar.
Now try removing one that is retaining a spring-loaded part on a shaft
without getting at least one bit hitting you in the face. And then try
putting it back without using laguage that would make an old sailor
blush.
