Need help with a part name

[Mrcheesecake]

Hi,

When changing the pull cord a piece went missing. It is the washer with the metal prongs that stick out of it that the screw goes into.

It is the piece in the middle.
What is its name, please help.

Is it one of these?

No sorry,

But not to worry I found it on the floor

My mower works again. Yay

Thanks for your help
