What's this bit called?

Evening all. I've been given an SKH 3 furrow conventional plough to pull behind my Nuffield and I am in the process of freeing all moving parts off with the view of taking it to a local ploughing match or two. Unfortunately I can't find a photo of it just right now but I will post one when I can, it's a heavy looking thing with sprung discs and hydraulic resets and manual vari width.

Anyway, on to my question. While taking the disc mechanism apart I broke the 3/4 circular clip that holds the disc mechanism on the 1 1/4 inch shaft that connects it to the beam.

Question 1, what do you call this type of clip, is it a circlip or not really?

Question 2, where would I get some more, are they easily available parts or am I as well making a new one with a washer and a bit of grinding and welding?

I've been trying to find clips but have not had much success on the Internet

Here's a picture:

Agreed on the E clip but I think your plough is metric so 32mm not 5/4".
