５ａ，３ａを形成していた。2. Description of the Related Art For example, a connector 1 as shown in FIG. 21 is used as a means for mounting a thermocouple protection tube at a predetermined position. The connector 1 includes a body 3 into which a thermocouple protection tube 2 can be inserted, a nut 4 that can be screwed into one end of the body 3, and ferrules 5 and 6 disposed inside the nut 4. The peripheral surface of the ferrule 5 and one end of the body 3 are formed with tapered surfaces 5a, 3a which can be engaged with each other.
