Patent ID: 8534971

Claim:
A clip operable by hand or with a tool for extending through and for clamping together a first workpiece with a first through-hole and a second workpiece with a second through-hole aligned with the first through-hole; the clip comprising: a bushing including a body and a bushing flange, the body extending axially downward from a first end to a second end, and the bushing flange extending radially outward from the first end of the body, and the bushing partially defines an internal cavity extending axially within the bushing, the internal cavity axially open at the first end through a leg hole partially defined by the bushing flange and axially closed at the second end by a leg spreader, and the bushing body includes a first projection extending radially inward into the cavity and a second projection extending radially outward into the cavity, and the second end of the bushing body includes a fastening projection; a pin including a pin flange and a leg, the leg extending axially downward from a connected flange end to a free tip end, and the pin flange extending radially outward from the flange end of the leg, and the tip end of the leg is radially spreadable and includes a first lock projecting radially inward, and the leg further includes a second lock projecting radially outward and located axially between the pin flange and the first lock; and the pin is located coaxial within the bushing with the pin leg extending axially through the leg hole into the cavity of the bushing body; and the pin is axially movable within the bushing from a temporarily coupled position to a fully coupled position; and wherein the temporarily coupled position the tip end of the pin leg is axially proximate to the bushing flange at a radial inward first position inside the bushing body, and the second lock on the pin leg is axially above the first projection in the cavity while the first lock is axially below the second projection in the cavity to prevent unintentional axial movement of the pin; wherein the fully coupled position the tip end of the pin leg is axially proximate to the second end of the bushing body and bent by the leg spreader to a radially outward second position outside the bushing body, and the first lock is axially located and engaged below the fastening projection to prevent inadvertent movement of the pin toward the temporarily coupled position.
