ABSTRACT OF THE DISCLOSURE A watertight slide fastener comprises a resilient bifurcated seal member mounted on opposite stringer tapes adjacent to one end of a pair of rows of coupling elements and snugly receivable in a Y-shaped guide channel in a slider body. The seal member has a pair of resilient tongues extending from said one end of the rows of coupling elements along opposed inner longitudinal edges of the stringer tapes and a head interconnecting the tongues at their front end so as to define therebetween a first opening opening toward said one end of the rows of coupling elements and snugly receivable therein a neck of the slider body when the slider is in its uppermost position. The tongues have outer sidewalls sealingly engageable with side flanges of the slider body and opposed inner sidewalls sealingly engageable together when the slider is in the uppermost position. The invention provides improved protection against water leakage particularly between coupling elements received in a slider body when the fastener is fully closed.
