Hello 91EACH I commented that what you mark with the blue arrow in that image is not where the thermocouple goes, there goes a shaped pipe, which has a Mayan wire woven in its base, which is held by two steel wires that make the times of grip and tensioners to prevent them from falling, the thermocouple of the Longvie, those, goes below entering the lighter until making contact with the flame of the pilot, can go loose but better place a clamp for the grip with the lower part of the Lighter, Luck and your orders for new queries.
