Mk1 Carpeted Battery Cover Nut Query

I decided before the good weather leaves us tomorrow to get the battery out for a top-up charge.
In putting it back in and clipping the battery cover back in place, it reminded me that I always wondered…

Is there meant to be a retaining nut on the screw thread the carpeted battery covers’ plastic connector holds on to (next to the rear light)?
( or is it just just held in by the plastic catching on the screw thread and then relying on the poppers to stop it moving when the vehicles in motion).

Thanks :slight_smile:

Yes there should be a plastic nut to hold the battery cover.

Thanks.
