Claim 8:
9. A cellular confinement system comprising:
(a) a first unitary web 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;
(b) a second unitary web 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;
(i) at least one open slot of the first unitary web of cells being aligned with at least one open slot of the second unitary web of cells to result in a cell overlap region; the cell overlap region having opposite first and second sides; and

(c) at least one connection device fastening the first unitary web of cells and the second unitary web of cells together; the connection device including:
(i) an insertion member having first and second opposite insertion ends and an insertion member extension therebetween;
(A) the insertion member being located on the second side of the cell overlap region;

(ii) an integral shank extending from the insertion member extension;
(A) the shank extending through the cell overlap region by extending through both of the aligned one open slot of the first unitary web of cells and the one open slot of the second unitary web of cells;

(iii) an integral handle member extending from the shank at an end of the shank remote from the insertion member;
(A) the handle member being located 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 against and covers the open slots on the first side of the cell overlap region.
