CONNECTION DEVICE

The invention provides a cellular confinement fastening system, a connection device for cellular confinement system, and a method for fastening two expanded cellular confinement structures by using connection device. The connection device comprises insertion member having first and second opposite insertion ends and an insertion member extension therebetween. An integral shank extends from the insertion member extension and is spaced from each of the first and second tapered insertion ends. A handle member extends generally from the shank at an end of the shank that is remote from the insertion member. The handle member has first and second handle ends and a handle member extension therebetween. The shank is spaced from each of the first and second handle ends. A cellular confinement system includes first and second unitary webs of cells made from elongated plastic strips bonded together in spaced apart areas. At least one connection device fastens the first unitary web of cells and the second unitary web of cells together through aligned open slots, thereby providing endurable connection.
