Which (if any) of those do you think requires there to be an external mechanical means of keeping the lever of a 221 closed (if it is to be 'MF')?

Nothing that I can see.
If that is required, presumably a requirement of the manufacturer of the connectors, the box, or both.

Thanks. Does that mean that you disagree with ...

Wago 221 for example require the levers to be held closed by the enclosure, which this box does not.

??

Furthermore, does this mean that you believe that if a connector passes the required BS5733 tests for being 'MF', that some sort of cable restraint is provided and the connectors are in some sort of enclosure, that the entire setup is 'MF', regardless of the nature of the enclosure?
