Abstract

Permanent closure, of the type comprising a part of male and a part of female, respectively joined to two sheets to be related by superposition, characterized in that the male part is integrated by a flat base that is joined to one of the sheets, of which base protrudes perpendicularly a core that passes through the sheet itself and has its free end with an outer rim, and the female part is formed by a flange that is retained in the other sheet and extends in its central area to form a groove that it passes through the sheet, forming in the groove a wall through which an axial passage is established in the part of the female, which wall is provided with at least one longitudinal cut from the mouth, to which a throttling for the axial passage, this mouth being of smaller contour than the rim of the core in the part of the male, so that, introduced the nucleus in the passage of the part hem bra by the opposite side to his mouth, the edge of the nucleus overcomes the mouth of the step by the elasticity that the cuts give him, to then establish a reciprocal retention by application of the mouth on the rim, making separation impossible.
