Abstract

La présente invention concerne un couvercle antivol pour un boulon et un écrou. Plus particulièrement, dans un état dans lequel un axe fileté d'un boulon est introduit à travers des structures et un écrou est vissé sur ledit axe fileté pour combiner les structures par la force de serrage du boulon et de l'écrou, le vol du boulon peut être évité en recouvrant l'extérieur de l'écrou par un couvercle. Ledit couvercle est caractérisé en ce qu'il comprend : un couvercle dont le côté inférieur est ouvert pour couvrir l'écrou quand l'écrou est fileté sur l'axe fileté du boulon traversant les structures ; et un couvercle de protection comprenant un élément de fixation d'écrou apte à retenir l'extérieur de l'écrou dans un état dans lequel l'extérieur de l'écrou peut tourner arbitrairement à l'intérieur du couvercle.
