ABSTRACT:
Disclosed is a bayonet catch for directly securing an electrode in a glass envelope which comprises projections extending inwardly from the envelope and radially extending portions on the electrode which are clamped between the projections upon rotation of the electrode. The material of the envelope and the electrode have substantially equal coefficients of expansion to minimize relative movement between the envelope and the electrode with changes in temperature.
