I do not know the name to search for a supplier of the washer.

The washer fits in a slot to retain a hexagonal bar in a hexagonal
hole.
I tried to search for a C-shaped locking washer unsuccessfully.

Circlip, E Clip or U Clip?


Any polite suggestions would be most welcome.

That takes all the fun out of it :-)
