A reclosable plastic bag ( 10 ) having two panels ( 15 ) of plastics sheet or film joined to, or integral with, each other, or a combination of both, to define a bag with an opening ( 13 ), with separable fastening means ( 14 ) of one or more interengagable elongate fib/groove configurations ( 14 a, 14 b) are provided to close the opening ( 13 ). A slider ( 100 ) is positioned in straddling relationship to the fastening means, and includes a support member ( 111 ) over-lying the opening to the bag and straddling the fastening means, and also carrying a separating finger ( 112 ) to engage with and separate the fastening means when the slider is moved to a first end of the fastening means in a bag opened condition, and a pair of legs ( 113 ) extending from said support member to force the fastening means into interengaging relationship when the slider is moved to a second end of said fastening means in a bag closed condition. Flanges ( 119 ) on the legs extend beneath the fastening means to retain the slider on the bag. The edges ( 19 ) of the panels of the bag adjacent the second end of the fastening means are bonded together with a portion thereof between the bonding and said fastening means being crimped to define a torturous path ( 20 a) between the panels into which path the separating finger ( 112 ) the slider is received to be gripped by the portions of the panels on either side of the torturous path to thereby retain the slider in the bag closed condition.
