A magnetic
fastener (1) including a first detachable fastening member (10) and a second detachable fastening member (20), said first and said second detachable fastening members (10, 20) respectively include a first and a second magnetic
coupling surfaces (34, 64) which are magnetically attracted towards each other along an axial magnetic
coupling direction, said magnetic
fastener including guarding means (99) adapted to
resist relative lateral movements between said first and said second magnetic
coupling surfaces (34, 64) when said first and said second fastening members (10, 20) are under magnetic coupling, said first and second fastening members include cooperative catching means (391, 991) adapted to
resist disengagement of said first and second fastening members (34, 64) generally along said axial magnetic coupling direction when said first and second fastening members are simultaneously under magnetically coupling and subject to lateral tensions applied transversally to said axial magnetic coupling direction.
