PROBLEM TO BE SOLVED: To prevent a damage on a female contact by eliminating an abut of a male contact even for a projected fixed contact point while maintaining a high function of wrench resistance. SOLUTION: A bottom wall 2, side walls 3 erecting on both ends in the crosswise direction of the bottom wall, an outer ceiling wall 4 and inner ceiling wall 5 extending to ceiling edges of the opposing side walls and overlapping each other form a pipe shape part 1 for inserting a male contact from the front side on a female contact F. An inside thin part is formed by crushing an inner surface of a front edge on the inner ceiling wall to form a step in the plate thickness direction. An outside thin part is formed by crushing an inner surface of a front edge on the outer ceiling wall to form a step in the plate thickness direction. The step on the front edge of the inner ceiling wall is formed corresponding to the crashed margin of the outside thin part in the plate thickness direction, and is overlapped on the outside thin part.
