A locking slider for sliding clasp fasteners is provided with a locking spring member for locking the slider into position on the fastener. The locking spring member is formed from a strip of stainless steel into a desired shape, the strip having an area higher in the cold rolling modulus than the remaining areas, such that the resiliency inter alia of the formed locking member is increased to an extent sufficient to withstand severe external stresses. |
