A very common kind of clasp used for joining two ends of a necklace. The clasp itself consists of a hollow metal tube in a circle shape with a gap in the side. The hollow tube contains a small wire held in place by a spring inside the tube behind the wire. The wire can be pulled back by means of a small knob which slides along the outer edge of the circular tube. Releasing the knob allows the spring to push the wire forward closing the gap. The other end of the necklace terminates in a small ring. By using the knob on the spring ring to open the gap in the hollow circular tube, one can then place the small ring through the gap and close the wire through the ring securing it in place and closing the necklace.
