Abstract
An implantable polycarbonate fastener for holding erosion cloth on the ground. The fastener has a long vertical leg, a shorter vertical leg extending parallel to the long leg, and a horizontal top leg extending between them. The long vertical leg has a tapered lower end segment with a downwardly and outwardly inclined inside face to cause the long leg to bend away from the shorter vertical leg as it is driven down into the ground, thereby making the implanted fastener harder to pull out of the ground.
