Adding new double sockets

[Mr_Freeze]

Hi Guys,
I'm adding a couple of double sockets to an existing circuit in my home.
I want to keep the integrity of the ring but the only place I can find to break into it easily is in another double socket close by.
If I run 2 x new cables from the existing to my new ones am I doing anything wrong by taking one of the original cables and jointing it through in the back of the socket box to one of the new cables and then simply fitting the other new cable back into where the original came out?
I understand it works electrically ok, more is there anything in the Regs I'm doing wrong by jointing in the back box?
Also I intended to use insulated crimps rather than connector block.
Comments?

Have you got any test kit?

yes mate, I'm a sparks, just not domestic so not familiar with House Regs.

House regs are no different to industrial or commercial.

I'm an ex mining electrician, we couldn't really join cables in the back of joint boxes in the environment I worked in.
Is it ok to do it this way or not?

If you are a spark you might get more help over in the Electrical Forum rather than the DIY forum.

There are some really helpful people on here but also plenty of wind up merchants too!

Can you not reroute one of the cables to 1 of the new sockets? Then make your ring from there?

Yeah that would've been ideal but without major disruption this was the easiest option.

Seems fine what you are proposing assuming the existing socket is part of the ring final. Most people these days would use Wago connectors to joint the conductors.

Just make sure they are flameproof enclosures for the sockets and the ring final circuit is intrinsically safe and your fine
Mr Freeze ,just crack on with your suggested method

Now your talking my language

Unless they are indent crimps, don't crimp it (standard insulated crimps are designed for stranded cable and may not provide a reliable joint over a period of time). Get yourself some Ideal in-line splices:-
