A device for mechanically joining sheet material, comprising a separable fastener which may have a pair of complementary extruded plastic members provided with resiliently separable interlocking fastener profiles, and at least one, and generally both, of the fastener members having releasable jaw extension structure for receiving and gripping and retaining sheet material to be joined. In certain forms, the jaw structure includes locking bar means arranged to be inserted into a cavity of the jaw structure. The jaw structure may be extruded from a plastic of greater durometer than the interlocking profiles.

Two margins on substantial expanses of sheet material and a device for mechanically joining the margins, and comprising: said device having a pair of complementary extruded plastic, elongated separable fastener members each of which has a body provided with complementary resilient rib and groove fastener means adapted for separable interlocking for maintaining said members in a separable fastener assembly; and each of said members having integrally on and along its body, and laterally spaced from said fastener means a respective releasable sheet-margin-gripping resiliently manipulatable jaw structure; said jaw structure of one of said members extending along one side of the assembly for retaining one of said sheet material margins in attached relation to said one member and thereby to the assembly, and the jaw structure on the other of said members extending along the opposite side of the assembly for retaining the other of said sheet material margins in attached relation to said other of said members and thereby to the assembly; and one of said sheet material expanses extending from its margin retained in one of said jaw structures and in partially wrapping relation across said assembly and into grip-enhancing thrusting relation to the other of said jaw structures, and the other of said sheet material expanses extending from its margin retained in said other of said jaw structures and in partially wrapping relation across said assembly and into grip-enhancing thrusting relation to said one jaw structure.
