That, or a BIC lighter. I've used both with equally good results. But don't let the flame actually touch the heat-shrink, it will melt and burn it.
And a pencil-type soldering iron works good too, and is safer than an open flame. Simply rub the hot soldering iron shaft on two or three sides of the heat-shrink. Doesn't take much, just long enough to get it shrunk down. Rub it, don't hold in one spot, or it could get too hot and melt through.
