Hi, ** Please ignore as I have found the answer.
I need some retaining clips in 8mm.
Unfortunately I don't know the name of the clips.
They are round with2 or 3 teeth facing inwards, something like an E clip but a full circle.
I have seen them on cars for retaining spindles or to stop something coming off a spindle.
They can be pushed on but resist moving in the other direction.
Has anyone got an idea what they are called please?
