You should not solder the pin that comes from the tube. You could crack the glass by applying heat.(even very small, invisible ones along the pin)
The pin is made from a kind of metal that can't be soldered very well. It is more for a good bond with the glass and has the same expansion-coefficient (i hope this is the right word)
Best way is to wrap the blank wire around the pin and seal it of with a tube filled with siliconkit. (take the one without acids..)
The metal clamp from the connectorstrip works fine too but take care not to apply too much force when you fasten the screws. If you can find headless-allenscrews that fit in the block (i expect something like M3), you can fasten them with minimal force and even cap it with a filled tube.
Ok, when you want to replace the tube you have to cut it. But if it cracks.... it need to be replaced anyway.
