Abstract
Abstract A system and a device for use in that system is provided for maintaining or tying down a flexible sheet material in a desired position. The device comprises a tie-down having two end portions connected by an elongate flexible link such that the end portions can be brought together by bending or flexing the link causing the latter to form a loop which can be secured to a scaffold bar or other anchor. The end portions are preferably hemispherical in shape and have surfaces which engage each other when the end portions are in their brought-together position. The end portions are substantially larger than the link so that when they are brought together and enveloped by the flexible sheet material, a cord or other securing means can be positioned at the juncture between the link and the brought-together end portions to secure the sheet material to the tie-down.
