A multipart plastic slider for straddling relation with a profiled plastic reclosable fastener particularly suited for thermoplastic bags and the like formed by a pair of flexible plastic sheets having a top edge with separable fastener means extending along the length thereof comprising reclosable interlocking rib and groove profile elements on the respective sheets, the straddling slider for closing or opening the reclosable fastener elements comprising a wedge-shaped separator finger and interlocking complimentary structure formed from plastic for moving along the fastener, the complimentary structure comprising a transverse support member having the wedge-shaped separator finger depending therefrom, said support member having interlocking structure on the opposite sides thereof, a pair of spaced depending side walls supported on said support member for engaging and automatically interlocking with said interlocking structure, said depending side walls extending from an opening end of the slider to a closing end, the side walls being spaced wider apart at the opening end to permit separation of the rib and groove elements by the wedge-shaped separator finger extending between the side walls at the opening end, the side walls being space sufficiently close together at the closing end to press the rib and groove elements into interlocking relationship as the slider is moved in a fastener closing direction, at least one of said separator finger and said side walls having shoulder structure on the bottom thereof for cooperating with the bottom of the fastener to prevent the slider from being lifted off the top edge of the fastener while the slider straddles the fastener.
