Abstract: A clasp for securing two items together includes a first section, a second section, least one pin and a force mechanism. The first section defines a cylindrical passage opening to the first face. The cylindrical passage defines at least one longitudinal J-shaped groove disposed longitudinally along the cylindrical passage. The J-shaped groove includes a main longitudinal portion, a transverse portion and a hooked portion. The second section has a top portion and a piston portion. The piston portion is complementary in dimension to the cylindrical passage. The pin extends transversely to the piston portion and is complementary to the J-shaped groove. The force mechanism applies a repulsive force between the second section and the first section so that when the pin is aligned with the hooked poration, the repulsive force drives the pin into the hooked portion, thereby inhibiting the second section from disengaging the first section.

Abstract: Necktie structure made of a plurality of articulated wood panels. One of the panels is shaped to simulate a four-in-hand knot portion of the necktie and a second panel is shaped to simulate the body portion of the tie. A third triangular panel is disposed in edge-to-edge relation with the lower end of the second panel. The panels are hinged together at their adjacent edges to form an articulated, coplanar structure. A flexible neckband for encircling the neck of the wearer is affixed to the undersurface of the knot-forming panel.
