An interdigitating fastener having an extruded slit core strip embedded in an extruded slit carrier strip. The core strip is slit in a serpentine manner to define interdigitating exposed portions and includes mechanical interlocking means for retaining each half of the slit core strip in the corresponding carrier strip portion to define a pair of separable assemblies adapted to be connected together and separated selectively by means of an associated slider. In one form the slider is provided with a wedging diamond which extends sufficiently to engage the carrier above and below the core strip and in a second form the slider includes a diamond which engages only the carrier strip outwardly of one face of the core strip. The fastener is economically manufactured by extruding the core strip, slitting the extruded core strip to define the serpentine interdigitating portions, extruding a carrier strip about the slit core strip and slitting the carrier strip to define a pair of core and carrier strip assemblies. |
