<p>A slide-type fastener which has mating halves (11a,11b) of which one has an elongate, lengthwise-extending bead (12) and the other has a laterally open elongate, lengthwise-extending recess (13) is adapted to receive said bead (12), the fastener is capable of interengagement such that the bead (12) is introduced laterally into and removed laterally from the recess (13) and is adapted so that when the bead (12) is in the recess (13), applying lateral tension between the said two halves (11a,11b) applies no uncountered force which removes the bead (12) from the recess (13). </p> |
