Now I can replace all the twist caps in my house
They are the best. Did my entire home installlation using them, it was such a breeze compared to Lüsterklemmen, whatever they are called in English.
The English term for those are wire nuts. They suck but they’re great in a pinch
Hm, nah, I meant these:

Not great, because if they change temperature a lot or are over torqued they lose pressure after a while.
Those wire nuts look even worse though, do they just screw on top of twisted wire ends to isolate them somewhat?
Yes, that’s them. The Marettes as the other answer suggested look even more sketchier, jeez, twisting wires and calling it a day for for up to 32A?
Anyway, I’ve found over torqued screw blocks in my parents home that lost pressure due to slight plastic deformation of the copper wires over time and that’s something you’ll never find out until the connector box starts smoking 0_o
