A retractable and rolling shutter characterized by the fact that each of the horizontal slats that make it consists of two pieces preferably made of aluminum, which can be coupled together, one of them being the base of the other that can slide longitudinally as a sliding cover , the base being made by a sheet forming a broad front face, is bent superiorly and inferiorly at right angles and in the same direction determining a narrow upper plane that follows, also by bending the sheet, a longitudinal channel whose edge external rises to the same level as the referred plane, and a wider lower plane that coincides with the vertical plane of symmetry of the upper channel, bends down forming a narrow flange on which and simultaneously on the edge external of the upper channel, they adapt with the possibility of sliding along their respective upper and lower bends of fitting of the sliding piece in which a frontal plane equal and parallel to that of the base piece is determined and a narrow lower plane at the same height as the bottom of the other piece, whose amplitude is precisely so that when the blind, the downward bend that follows it, lodges in the center of the hole that in the lower immediate blade determines its upper channel.
