Abstract: The present invention involves a dart having a dart shaft that can be snap-fit into a corresponding dart barrel. The dart shaft has a cylindrical projection that terminates in a flange having indentations or detents on its peripheral surface. The dart barrel has a recess; flexible elongated arms extending into the recess of the dart barrel, removed from the walls of the dart barrel for clasping the dart shaft. The arms have indents or detents corresponding to the indents or detents of the projection, and the arms flex on and off the cylindrical projection of the dart shaft as the indents and detents are aligned and adjusted. The invention further relates to an adapter that can be used to modify a conventional threaded dart into the snap-fit dart of the present invention.
