An improved slide fastener assembly incorporating an arrangement in which the stringer tapes of the fastener may be sewn into a garment prior to assembly with the slider and wherein the slider may then be assembled to the stringers without force. Upon such assembly the parts remain assembled by virtue of cooperating fastener elements having projecting portions that interengage with each other and the slider to prevent retrograde movement back out of the slider following assembly. |
