Very simple & good!

To assemble:
Installation is super easy and it requires no tools except a stripping tool. The sheath of the cable but you can also easily cut with a knife and then remove it.
1. Strip completely from the cable beginning approximately 6.5mm.
2. Then 6.5mm Strip again, but this time only the outer shell.
3. The mesh now turn over the outer sheath.
4. Now just plug it slide to the dielectric (internal insulation) flush
is flush with the contact surface in the plug.
5. Done.

It all fits beautifully.
The rubber rings can be stuck over it outdoors, indoors, these are not necessary.
