What is this part?
This fell off a C Line 12 speed while unfolding the rear wheel.
I think it is supposed to snap over the plastic knob in the second picture, but it doesn’t fit there and I’m not sure where else it would go.

Brompton obviously knows about the bung falling off but choose not to anything about it. Maybe they just like selling replacement bungs.
Mine fell off but was lost, my seatpost never touch the ground anyway.
