Abstract: An improved telephone subscriber circuit protector module particularly suited for use in interconnecting with protector blocks having exposed quick clip terminals on an exposed surface thereof. The module features a relatively few number of metallic parts, and can be assembled with a series of simple hand operations. A three-element gas tube is employed in which the contacts are formed with elongated extensions, the extensions providing interconnections with contacts in such manner as to maintain the contacts in operative position when the module is assembled.
