Abstract

La présente invention concerne un couvercle de sécurité d'une prise de courant. Selon l'invention, après le couplage d'un boîtier à un trou d'insertion de fiche, un élément rotatif est poussé contre une partie saillante à l'intérieur du trou d'insertion de fiche, et fixé à ladite partie, au moyen de la rotation d'un élément poignée, rendant ainsi difficile pour les enfants en bas âge, ou plus âgés, de séparer le couvercle de sécurité de la prise de courant.
