The UK plug is probably not as tightly secured, but the pins are rectangular and almost twice the width of the round CEE pins. I think the result is it's pretty much equivalent.
There are Youtube "tutorials" about how to plug CEE appliances in the UK, for example: https://www.youtube.com/shorts/AMGKtNtSaHI . In UE we have sockets with unearthed barriers using closed holes when the plug isn't earthed, but they also sell plastic pieces as a workaround for the barriers. I have seen people breaking or sliding the barriers with a screwdriver to get access. At this point is better to just install spring covers like the triphasic sockets, because the only real protection is against dust.
