A device for releasably fastening a cover slab to the opening of a crypt or niche extending back from a vertical support wall. Each device is positioned at a common point of adjacency of a plurality of slabs. Each device has a rotatively mounted locking plate for engaging slots in the sides of each of the slabs. The plate has a cutaway sized and dimensioned to allow for the passage of one of the slabs through the cutaway when the cutaway is rotated into proper alignment. A keyed tool may be used for turning the plate indicating the positioning of the cutaway. The plate is mounted to allow minor axial, pitch and yaw movement and is biased toward an axially perpendicular orientation.
