提供することを課題としている。In the above-mentioned conventional clamp, if the clamp is covered with a protector from the clamp to the wire anchor, it has sufficient strength against bending. As shown in the figure, the so-called protectorless type of retaining clamp that does not use a protector is relatively soft structurally near the base of the handle 13,
Since a large bending moment is applied in the thickness direction when the wheel P is passed, plastic deformation is likely to occur. On the other hand, it is conceivable to increase the thickness of the eye portion 13b. However, the mating connecting member such as another tension member to be retained on the steel tower after the wire drawing must be changed to correspond to this. It is difficult to change the thickness of the eye portion 13b. Therefore,
SUMMARY OF THE INVENTION It is an object of the present invention to provide a handle of a retaining clamp with improved strength against bending so that the handle is not deformed when passing through a wheel.

にそのまま連結することができる。In the retaining clamp 1 of the present embodiment,
At the time of passing the wheel P in the wire drawing work, the wire W is bent from the wire W to the retaining clamp 1 along the outer periphery of the wheel P. At this time, when a bending moment in the thickness direction is applied to the eye portion 4b of the handle 4 of the retaining clamp 1, the base of the eye portion 4b is formed in an arc shape by the concave portion 4c.
The base 4a is thicker at both ends than the center of the base of the eye 4b, and the eye 4b is supported by the base 4a, so that the eye 4b is reinforced against bending. There is no easy deformation. On the other hand, when the wire 4 is bent in the direction of the plate surface of the eye 4b of the handle 4 from the wire W to the retaining clamp 1, the connecting piece C1 of the wire locking tool C freely swings in the recess 4c without any trouble. It should be noted that the pull 4 of the retaining clamp 1 is a wire locking tool C connected to a conventional pull.
Can be connected as is.

An eye portion 4b which stands substantially at a right angle from the portion 4a, overlaps with the wire locking member C and is connected by a connecting pin, and a concave portion 4c for receiving the distal end portion of the wire locking member C is provided in the base portion 4a. The base portions 4a at both ends of the base of the eye portion 4b are made thicker along the concave portion 4c, so that the strength of the puller of the so-called protectorless type retaining clamp can be improved. Even if a large bending moment is applied in the direction, no plastic deformation occurs, the conventional wire locking tool can be used as it is, and the necessary swing range can be secured. It has the effect of.
