15A connectors are not suitable. The current in any single cable in a
ring circuit can exceed that.

Be interested to know just how a 15 amp connector block differs from the
terminals found in a 13 amp socket?

They will be tested to different specs at the least. However the quality
of socket terminations does vary greatly. Some do seem only just up to it.

(the TLC "ultimate" ones being my current favourite - nice large open
square terminals that come with the screws already open, nicely colour
coded for old and new wires, shallow depth fitting, decent earth
terminations (x2) etc. And they are an attractive design as well)

The diameter of the hole is similar as are the fixing screws. If the
cables being jointed are overlapped over the entire length of the
connector so both screws grip both I'd say they'll make an excellent
connection well up to handling any current the cable can.

The terminal current rating almost certainly assumes you are not
overlapping the wires...
