Abstract: A device for releasably fastening up to four adjacent slab corners to a support wall or ceiling. The device is positioned at a common point of adjacency of a number of slabs. A locking disk having a quadrant notch is rotatively mounted orthogonally to the surface of the slabs, and engages or disengages slots cap in the thickness of the slabs according to the angular orientation of the disk. The device is capped by a decorative rosette having an appendage projecting loop bracket shaped and dimensioned to accommodate a bud vase. The device is particularly indicated for fastening slabs used to cover adjacent funerary crypts.

Abstract: 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.
