Small, glass bulbs with neon (maye also some other gas?) used 
sometimes as indicators. You even get a visual confirmation when 
they conduct an ESD:)

Depending on the type, the breakdown voltage ranges about 60-200V. 
They were relatively cheap when I was experimenting with them for 
this same purpose, about 10 years ago. Much less expensive than gas 
filled spark arrestors. They present very small capacitance to the 
signal. They are just two short pieces of thin wires at several 
millimeters from each other, immersed in gas.

They are not good if there is DC voltage present, because once they 
conduct the DC voltage must go pretty low before they stop 
conducting.
