1. A fitting member for connecting a coaxial cable having an electrically conductive member to a second electrically conductive member, comprising:

  • a. a connector body having a first end, an opposite second end, a cylindrical body defined between the first end and the second end, and an annular recess formed on an outer surface of the cylindrical body proximate to the second end;

    b. an outer tube having a first end and an opposite second end defining a body therebetween and a clamp head inwardly projecting away from the first end, wherein the body has an outer diameter, d1, and is sized to fit into the first end of the connector body by the second end of the outer tube;

    c. an inner tube having a neck portion, a first shoulder extending from the neck portion, a second shoulder extending from the first shoulder and a sleeve extending from the second shoulder defining a tube body, wherein the second shoulder has a diameter sized to engage with the clamp head of the outer tuber, and the first shoulder has a diameter greater than the diameter of the second shoulder so as to form a first step at the junction of the first shoulder and the second shoulder for limiting the axial motion of the clamp head, and the tube body has an inner diameter, d0, and is sized to receive a free end of the electrically conductive member of the coaxial cable therethrough; and

    d. a sleeve tube insertable into the connector body for holding the coaxial cable, wherein the inner tube further comprises a flange outwardly projecting away from the junction of the neck portion and the first shoulder, the flange having a diameter greater than either of the diameter of the first shoulder and a diameter of the neck portion so as to form a second step at the junction of the first shoulder and the flange for limiting the axial motion of the clamp ring of the connector head, and a third step at the junction of the flange and the neck portion for partially receiving the first sealing member.
