I would call that a c-clip

Yes, 10s or even hundreds of tiny holes add up one giant hole. And no license required, just look up the very simple code.

Fantastic! Thanks for sharing,
Here in Perth I have a double brick house, would this be a worthy upgrade for air tightness in a brick house?
I’ve already adopted some of the major issues;
Manhole cover
Fans & extractors
And I’ve already noticed a substantial difference! Keep up the great work

Most brick installed PowerPoints and switches have a wall box behind, you can just silicone up the entry holes.
