ABSTRACT:
An invisible slide fastener includes thermoplastic slide fastener elements secured to folded-back portions of the mounting tapes. The slide fastener elements are molded onto the tapes so that integral fastening extensions of the fastener elements extend through an open mesh area of each tape. The slide fastener elements include an interlock structure which is particularly resistant to movement between the opposite rows of slide fastener elements.
