ABSTRACT:
A separable fastener especially suitable for heavy duty sheet-like enclosures comprises complementary, resilient hooked rib and groove closure strips having angular hinged flange connections for attachment to generally coplanar enclosure sheet margins capable of acting as expansion joints permitting a range of pulling apart of said margins without disturbing the interlocking relationship of the ribs and grooves of the fastener strips. A simple U-shaped slider can be employed to effect closing only of the fastener, and a pull flange is provided for opening of the fastener when desired, but only with a degree of difficulty.
