    caractérisé en ce que
    un mécanisme d'auto-verrouillage (62) est prévu, lequel fait tourner l'aimant permanent (12), lors de la fermeture de la porte (4), automatiquement de la position de libération à la position de verrouillage.
  18. Dispositif de fermeture selon la revendication 17,
    caractérisé en ce que
    le mécanisme d'auto-verrouillage (62) comprend une crémaillère (64) réceptionnée dans la zone de l'arête de porte et mobile par rapport à la porte (4) dans l'état monté, laquelle est en engrènement de dent avec une roue dentée (68) couplée avec l'aimant permanent (12), et est déplacée après la fermeture de la porte (4) par l'influence d'un effet de force magnétique en direction du cadre (2) fixe, et fait tourner alors l'aimant permanent (12) dans la position de verrouillage.
  19. Dispositif de fermeture selon la revendication 17,
    caractérisé en ce que
    l'effet de force magnétique est généré par un troisième aimant permanent (70) fixé sur la crémaillère (64), lequel coopère avec l'élément de fermeture (6) magnétisable et/ou une partie magnétisable du cadre (2).
