Claim 11:
12. A connection device for fastening two expanded cellular confinement structures; the connection device comprising:
(a) an insertion member having first and second opposite insertion ends and an insertion member extension therebetween; the first insertion end having a first end face, and the second insertion end having a second end face;
(b) an integral shank extending generally perpendicular from the insertion member extension and being spaced from each of the first and second insertion ends;
(c) an integral handle member extending from the shank at an end of the shank remote from the insertion member;
(d) a longitudinal axis extending through each of the insertion member, handle member, and shank;
(e) a plurality of barbs projecting from the insertion member toward the handle member;
(i) the plurality of barbs including a first barb adjacent the first insertion end; the first barb having a beveled surface forming a ramp angled relative to the first end face and extending along a plane intersecting the longitudinal axis in a vicinity of one of the shank, the handle member, or a space above the handle member;
(ii) the plurality of barbs including a second barb adjacent the second insertion end; the second barb having a beveled surface forming a ramp angled relative to the second end face and extending along a plane intersecting the longitudinal axis in a vicinity of one of the shank, the handle member, or a space above the handle member;

(f) a washer section between the handle member and the insertion member;
(i) the washer section having a first surface and an opposite second surface;
(ii) a side surface extending between the first and second surfaces; the side surface being along an outer periphery;
(iii) at least a portion of the outer periphery radially extending from the longitudinal axis being equal to or further than a radial outermost portion of the handle member and
(iv) 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.
