Watertight electrical connector

I initially designed this to connect two cables severed by the lawnmower :-)
Thought it might be usefull for someone else.
Basically, a small box with a self retaining lid that is filled with silicone sealant.
I decline of course any responsability in case of injury or anything else that might happen with this object.
I made two of them and it works like a charm. Silicone is used as a cable insulator. I do have to mention however that in my case those cable are on low voltage (24V).
