Nice work but still not up to code...

What you are seeing is only the 3rd step in making a wired connection 1st step strip the wires 2nd step make a tight mechanical twist 3rd step dip in tin 4th step secure connection with either a bolt type insulated connection or in this country a spring-loaded plastic wire nut 5th step dip in liquid insulation use heat shrink or moisture resistant tape to seal out air and moisture lastly also since it is not in the USA plaster the grove in the cement wall and cover the connection area with a removable inspection cover

Yep, you're right. Just checked my copy of NFPA 70 (2017) NEC:

300.15 Boxes, Conduit Bodies, or Fittings - Where Required. (A) Wiring Methods with Interior Access

Definitely NOT in the USA...

it's not even in most of the Middle eastern countries I have done work in. The new connection process is fine, but the existing connections I am seeing would be suspect and denotes there is at least 1 possibly more other circuits on the feeder line I see 3 wires on the connections meaning 2 circuits plus the existing circuit making a total of at least 3 circuits which in some instances would be acceptable but not when being branched off an existing termination never feed a connection off of another connection point. Either run the 3 or 4 branch circuits from a single connection with the feeder without an intermediate splice or better yet install a terminal box My electrical guys I had working for me in Kuwait would have taken one look at that and gone all the way back to the main panel to run new circuits

And the flux has wicked itself up the wire under the insulation, where it will sit slowly eating away at the wire.
