For a 2.5mm2 T&E cable use 12.7mm (0.5 inch) diameter heatshrink, for smaller cables 10mm diameter will probably be a better fit.
Also remember to fit sleeving to the earth wires, Slide the heatshrink it up one of the wires untill it is out of the way:
Select suitable crimps
For joining cables like this, the type of crimp required is known as a "butt" crimp or splice.
The crimp selected needs to not only match the wire size in question, but also have enough current carrying capacity for the circuit. The colour of a crimp only indicates its size, they are not designed to match any particular colour of wire insulation.
Crimp
Position the crimp in the jaws of the crimp tool (in the recess marked with the same colour as the crimp), and squeeze gently so as to grip the crimp without squashing it:
You should position the crimp so that the active part of the jaws are directly over the metal part of the crimp, leaving the empty part of the plastic insulation sticking out.
