A stop prevents the dart apparatus from being withdrawn one way. A seal held in a through slot near the other end of the dart apparatus prevents the dart apparatus from being withdrawn the other way. A cap is engaged to and spaced from the stop by a shaft. A tether is engaged to the shaft and a safety pin is engaged to the tether. The body, stop, cap and shaft are co-axial, integral and one-piece.
