Claim 10:
11. A kit comprising:
(a) a plurality of unitary webs of cells made from elongated plastic strips bonded together in spaced apart areas; the strips forming walls of the cells; at least some of the cells defining open slots that are alignable with open slots of adjacently positioned unitary webs of cells at cell overlap regions, the cell overlap regions having opposite first sides and second sides; and
(b) a plurality of connection devices usable to fasten together adjacently positioned unitary webs of cells through the slots at the cell overlap regions; each of the connection devices including:
(i) an insertion member having first and second opposite insertion ends and an insertion member extension therebetween; the insertion member being positionable on the second side of the cell overlap region;
(ii) an integral shank extending generally perpendicular from the insertion member extension and being spaced from each of the first and second insertion ends;
(A) the shank being positionable through the cell overlap region by extending through aligned slots;

(iii) an integral handle member extending generally perpendicular from the shank at an end of the shank remote from the insertion member;
(A) the handle member being positionable on the first side of the cell overlap region;

(iv) a longitudinal axis extending through each of the insertion member, handle member, and shank; and
(v) a washer section between the handle member and the insertion member;
(A) the washer section having a first surface and an opposite second surface;
(B) a side surface extending between the first and second surfaces; the side surface being along an outer periphery; and
(C) at least a portion of the outer periphery radially extending from the longitudinal axis equal to or further than a radial outermost portion of the handle member;
(D) the handle member having a wall extending from the first surface of the washer section without a gap between the wall and the first surface of the washer section;

wherein the washer section is provided to be placed against and cover the open slots on the first side of the cell overlap region.
