The present invention relates to a safety snap button capable of preventing loosening, which comprises: a female button having a penetrated inlet hole and a penetrated fastening hole which is interconnected with the inlet hole; a male button having a locking protrusion formed in a lower portion thereof which flows into the inlet hole of the female button and is fastened to the fastening hole; and a fastener which is connected to the female button and fastens the locking protrusion so as to prevent the locking protrusion from being escaped from the fastening hole when the locking protrusion of the male button flows into the inlet hole of the female button and is positioned in the fastening hole. When the locking protrusion of the male button is positioned in the fastening hole by being transported (slid) through a passage of the fastener in the state of being inserted into the inlet hole of the female button, a solid bond of the locking protrusion is maintained as the locking protrusion interferes with the transport by being hung at a central portion of the passage having a smaller width than the lower diameter of the locking protrusion, thereby inducing a stable bond of the male button and the female button. In addition, the present invention has an effect of securing use generality of a product by being able to strengthen the bond of the female button and the male button by adding only fastener configurations of a simple structure which are easily manufactured in ordinary female button and male button by injection molding. |
