What are they called?

As the subject..
They look like washers with wings internally and made of spring steel,
they are designed to slide
onto a bar in one direction only and act as a cheap nut. The seem to be
found in mass produced
items.
Once I know what they are called I can Google for a supplier.
I think they're known as "push-on fasteners" in the RS catalogue
