Since the tension removing body that regulates the movement of the wire due to the force in the drawing direction is provided on both inner walls of the wire drawing port, a constant tension removing performance can be obtained even if the diameter of the wire is different. At the time of joining, the force for pressing the electric wire in the joining direction is not required, so that the joining work can be easily performed.

Since the other end where the hooking claw to bite is formed is projected in the electric wire drawing port by inclining in the direction opposite to the drawing direction, it is possible to use a tension removing body according to the shape of the electric wire and change the housing. Without changing the tension removing body, the tension can be removed according to the shape of the electric wire.
