Abstract
A fastener for attaching a flexible cover or sheet, such as a canvas tarpaulin, to a structure to provide a cover for the structure, and also to provide an acceptable weather seal around the cover. The device comprises a channel member fixed to the structure to be covered, and used in cooperation with a lock member having a pair of bead portions attached to the cover. The bead portions are separated by a very flexible portion of material so that the outer bead portion will move easily with respect to the inner bead portion. The two bead portions are then inserted into the channel one at a time and once in the channel are held by a detent from releasing under normal tension loads on the cover.
