A venting slide fastener stringer comprising:

• (a) a warp-knit stringer tape including a pair of longitudinal warp-knit webs spaced transversely from each other, with a longitudinal wale-free region therebetween, and having a pair of marginal wales, respectively, confronting each other across said wale-free region, and a connecting thread having portions laid only in said marginal wales and substantially parallel adjacent portions all spaced longitudinally of and extending transversely across said wale-free region in a direction substantially perpendicular to said marginal wales, thereby defining a plurality of substantially rectangular vent holes longitudinally along said wale-free region, each of said webs comprising foundation threads constituting a plurality of wales juxtaposed across said each web, said marginal wales being composed of threads that are more rigid than said foundation threads;
• and
