1. A magnetic fastener assembly comprising
a first fastener part for attaching to a first engagement end of a first strap end and a second fastener part for attaching to a second engagement end on a second strap end, wherein the first and second fastener parts are detachably engageable with each other by magnetic coupling or attraction and comprise complementary engagement devices for making detachable engagement with corresponding complementary engagement devices on the first and second engagement ends of the first and second strap ends; wherein the first fastener part comprises a first fastener housing defining a first engagement device on a first longitudinal end and a first magnetic coupling surface longitudinally displaced from the first longitudinal end, and the second fastener part comprises a second fastener housing defining a second engagement device on a second longitudinal end and a second magnetic coupling surface longitudinally displaced from the second longitudinal end; wherein the first and second longitudinal ends are aligned in a longitudinal direction and on opposite longitudinal ends when said first and second fastener parts are brought into magnetic coupled engagement in a magnetic coupling direction which is orthogonal or substantially orthogonal to the longitudinal direction; wherein the first engagement device and the second engagement device are mechanically complementary and mechanically latchable, securable or engageable with each other when the first and second fastener parts are not in magnetic coupled engagement; wherein the second fastener housing comprises a second magnetic housing, the second magnetic housing including a second magnetic wall portion extending in the magnetic coupling direction and surrounding a second peripheral portion of a second magnet slab, and the second magnet slab comprising a bottom magnetic surface of a second magnetic polarity in magnetic abutment with the second magnetic housing and a top magnetic surface of a first magnetic polarity which is exposed to facilitate the magnetic coupled engagement, the second magnetic polarity being complementary to the first magnetic polarity; wherein the first fastener housing includes a first stop of a first magnetic polarity on a longitudinal end distal to the first longitudinal end, and the second magnetic wall portion discontinues at a location oppositely facing the second engagement device in the longitudinal direction to define a second receptacle to receive the first stop when said first and second fastener parts are in magnetic coupled engagement; and wherein the first stop projects in the magnetic coupling direction and is in magnetic abutment with the second fastener housing when said first and second fastener parts are in magnetic coupled engagement. |
