Such as a proper junction box, right?
It's a bit dangerous leaving a choco-block in mid-air (yes we're familiar with them in the States, and I used a 3-terminal block instead of the normal American marrettes when wiring up my fume hood - looks much neater and it is enclosed in the wiring panel of the hood).
There's always a danger of something falling into the recessed screw terminals or the entire thing snagging and pulling apart....same thing with Marrettes also I guess.
