Hmmmmmm..many thanks for the elucidation HA..

 

Not being funny or owt, but it looks like those wings have never been fiited in the in situ box before..

 

Them red clips are junk if it tight they hard to pull forward, take socket off and push it in

 

That's dot and dab for you Peter.

 

You need to buy cavity box doubt you can buy them separate some wholesalers stock them

 

Trim some of the rear of the lug off. The brass threaded ferrule only takes up the first 1/2" or so.

I've never seen them sold seperately. You buy the whole box, discard the body, and keep the wings.
Each manufacturer has a slightly different shape, so there's no 3rd party aftermarket 'one wing fits all' solution.

 

One alternative might be to get you electrician to disconnect the socket, totally remove the plastic box which will leave a deep hole.

Glue, using a grab adhesive, a suitable thick piece of timber to the wall behind the boards, then when dry screw a 35mm metal back box into place. Finally, reconnect the socket and screw into place.

 

I expect they are called "those little red clips/wing/lug things" for cavity wall socket boxes.
As they are so cheap to buy the whole box with the lugs then I think you would struggle to buy the lugs on there own.
These are what I used from our hosts:-
