Yes, An excellent type of tape for this application is the very sticky and a little soft Scotch number 27 "Glass Cloth Electrical Tape" from 3M, Austin TX, USA, most electrical stores have this in AU, its called class B insulation.

It sticks to the neck well but its fabric like surface is rough enough that only a little yoke clamp tightening locks the yoke well. Conrac appear to have used this on the necks of their crts quite a bit, not just where the yoke clamps, but also on the neck and first part of the bulb where the yoke would otherwise make contact with the glass.
