Connector

A connector comprising a female housing for containing terminal metals, a U shaped holder for holding end parts of electric wires extending in a lengthwise direction having a lock hole located substantially in the middle of a connecting wall connected between a top and bottom wall of the holder, said female housing and said holder being adapted to be engaged with each other,

• whereby said top wall forming a first wall of said holder and an upper wall forming a second wall of said female housing are overlapped on each other when said female housing and said holder have been engaged with each other, at least one of said first wall and said second wall is elastically deformed in a direction in which said first wall and said second wall move apart from each other when said female housing and said holder are engaged with each other;
• whereby said first wall and said second wall are brought into contact with each other by elastic restoring force when said female housing and said holder has been engaged with each other, and a width of said first wall in a direction perpendicular to the lengthwise direction of said electric wires is substantially equal to a width of said electric wires, and substantially equal to a width of said second wall, wherein said first wall is formed so as to be gradually thinner in thickness with said width, in a direction from said connecting wall toward said second wall.
