Abstract
Sealing devices are disclosed in which two members are connected through a hinge for clamping and sealing engagement with gathered-together material at the end of an enclosure. The hinge facilitates installation and accurately aligns interacting parts including a projecting structure on one member with an opening in the other, interengageable locking elements on side portions of the members and sealing elements on end portions of the members. The locking elements include a shoulder on one member engageable by a shoulder on a projection on the other, the projection being engageable in one embodiment for release. Additional locking elements are positioned adjacent the hinge connection for reinforcement.
