Abstract
A device for releasably retaining together in air-tight relationship the edges of a plurality of film layers which may be used, for example, in an inflatable structure. The device includes a pair of elongate strips, one of which is snapped into the other with the edges of the film layers positioned therebetween, thereby forming a seam at the film edges. The strips are preferably extruded shapes which are coextensive in length with the edges of the film to be sealed together. Means are provided for anchoring the strips to the ground after they have been engaged with the film layer edges, with the anchor means designed to enhance the locking force placed on the device.
