Mechanical closing for doors and windows, characterized by the fact that it is constituted by a spiral spring whose two ends have crazy turning rollers, which can be juxtaposed, pressing against each other, which springs are housed inside a bowl, in one of whose sides there are the appropriate recesses, through which the ends of the spring lodged inside the same emerge, which at its edge, has two divergent tabs, by which it is linked to the frame in question through of the appropriate through holes that each flange has while the male appendix disposed on the door leaf or window collides between the two rollers of the ends of the spring and these are separated enough to make way for the aforementioned male that is retained by pinching without being able to exit accidentally until a greater pressure overcomes the action of pinching of the spring and the rollers.
