A sliding clasp fastener is disclosed. The fastener comprises fastener strings of interlockable and U-shaped limbed fastener elements attached to respective fastener tapes by a line of stitching. The loops of the stitching pass over respective fastener elements to attach the fastener string to its fastener tape. Each string is anchored to its fastener tape by a filamentous element, such as a fine gauge cord or twisted textile thread, which meanders through spaces defined between the U-shaped limbs of the respective fastener elements in the longitudinal direction of the string. Also disclosed is a method of attaching a fastener string of U-shaped limbed fastener elements to a longitudinal fastener tape. The fastener tape and the string of fastener elements are fed past a stitching station at which a needle The an attaching machine is located. Te needle is used to insert a row of stitches to attach the fastener elements to the tape, and a filamentous element is fed in the longitudinal direction of the tape alternately in front of and behind the stitching needle transversely of the tape. The filamentous element passes through spaces defined between the limbs of the fastener elements to anchor the attaching stitching and hence to the tape.
