A slider having a connection post which is not manufactured in a normal forming process such as a pressing process, can be certainly and firmly produced in a simple manufacturing process. A slider comprises a pair of wings which are individually formed. In one wing, a joining protrusion protrudes from a connecting post, and is provided with an engaging groove or plural engaging grooves. In the other wing, a joining hole is bored in the other connecting post. Therefore, the joining protrusion is interengaged with the joing hole. Then, a part of the material of the other wing is plastic-deformed and flows into the joining grooves to join the both wings integrally so as to provide a desired slider body.
