A roller blind having a canvas, a winding shaft to roll up the canvas, a load bar, and two guides, each defining therein a cavity and being provided with a slit through which the canvas is inserted. The canvas includes on each of its side edges a hem, said hem being configured to be housed inside the cavity, wherein the hem forms a tube including therein a retaining strip. The cross sectional area of said tube is greater than the cross sectional area of the retaining strip, and said hem thickness is greater than the width of the slit into which it is inserted.
