Abstract

A permanent closing clasp which is characterized by being made up of three coupling parts, the first one presenting a wide base from whose center an appendage gives a suitably hard and elastic material carrying a large central longitudinal groove whose internal faces have a toothing of saw with inclination oriented towards the base; the second piece is composed of a sleeve of very similar length to that of the cylindrical appendage of the first piece described above and of internal diameter slightly larger than the external part of said appendix appropriately so that they can be fitted by plug presenting the sleeve at one of its ends and precisely the opposite to the penetration of the appendix a wide base that surrounds it so that once coupled the two pieces can be included between the two respective bases facing the material or materials on which you want to apply the clasp carrying out its fixation permanent by introducing by the free opening of the sleeve of the third piece which is a wedge-shaped pin which is made to penetrate precisely into the longitudinal groove of the appendage coupled with the sleeve, said pin having two opposite faces and respectively facing the toothing of the internal faces of the correspondingly corresponding slot jagged teeth of saw but with inclination in the opposite direction to that of internal teeth all this in a way so that the introduction of the spike leads to an irreversible link between the teeth referred to be definitely fixed said link by blocking the head of the pin it establishes on the piece that configures the sleeve in whose effect it has a larger diameter than the internal one of said sleeve.
