Abstract

L'invention concerne un dispositif de fixation adhésive mécanique comprenant une base présentant une première surface et une seconde surface opposée à la première. Ces deux surfaces présentent à leur tour des première et seconde zones. Le dispositif de fixation adhésive mécanique comprend une pluralité d'éléments d'accrochage par contact s'étendant de la première surface de la base des première et seconde zones. Les éléments d'accrochage par contact sont mécaniquement fixés à l'aide d'une matière de fixation adhésive de type boucle ou une autre matière. La base est pliée de sorte que les première et seconde zones soient opposées. Les éléments d'accrochage par contact de la première zone entrent en contact avec les éléments d'accrochage par contact de la seconde zone afin de maintenir la fixation adhésive mécanique à l'état plié jusqu'à que l'on la déplie manuellement de manière à exposer les éléments d'accrochage par contact des deux zones.
