Claim:
1. A clasp system for attaching two elements, comprising first and second parts each having a body for attachment to a respective one of the elements, the first and second parts having: a fastening means comprising first and second fastening portions, the first part including the first fastening portion and the second part including the second fastening portion, wherein the first fastening portion and the second fastening portion are respectively configured for clipping engagement; a further fastening means comprising first and second further fastening portions, the first part including the second further fastening portion and the second part including the first further fastening portion, wherein the first further fastening portion and the second further fastening portion are respectively configured for clipping engagement; wherein the first part further comprises a pivot pin extending therefrom located between the first fastening portion and the second further fastening portion, the pivot pin having an axis; wherein the second part comprises a pivot pin recess therein, located between the second fastening portion and the first further fastening portion, the pivot pin recess being configured to receive the pivot pin, wherein the pivot pin and the pivot pin recess are respectively configured to permit angular movement of the pivot pin in the pivot pin recess about the axis; wherein the first and second fastening portions and the first and second further fastening portions are arranged so that the clipping engagement of the first and second fastening portions and the first and second further fastening portions is simultaneous and fastens the first part and the second part together; wherein unfastening comprises a relative twist movement of the first and second parts about the axis of the pivot pin to unclip the first and second fastening portions and the first and second further fastening portions; wherein the first and second parts further comprise magnetic material arranged to pull the first and second fastening portions and the first and second further fastening portions into the clipping engagement when the first and second parts are relatively oriented in a predetermined manner and spaced less than a predetermined maximum distance apart; wherein the magnetic material comprises: a first magnetic element located in the body of the first part between the first fastening portion and the pivot pin; a second magnetic element located in the first part between the second further fastening portion and the pivot pin; a third magnetic element located in the second part between the second fastening portion and the pivot pin recess; and a fourth magnetic element located in the second part between the first further fastening portion and the pivot pin recess; wherein the first magnetic element and the third magnetic element attract each other, the second magnetic element and the fourth magnetic element attract each other, the first magnetic element and the fourth magnetic element repel each other, and the second magnetic element and the third magnetic element repel each other.
