A device for adjusting the tension of the return spring of a mosquito net, a roller curtain or the like, comprises a sheet-bearing roller (1) with a sheet (2) mounted rotatably around its own longitudinal axis under the effect of a return spring (25), on a head (4) with return spring (25) and on a head with bushing in a closure roller shutter box (3), said return spring (25), mounted through a sleeve (21) within the sheet-bearing roller (1) and anchored, at one of its ends, to a first support element (17) in proximity to the head (4) with return spring (25) and at the other end to a second support element (170) able to slide without rotating within the sheet-bearing roller (1). The head (4) further comprises a worm screw assembly (13,14) able to be operated from the exterior with the mosquito net mounted, able to vary the tension of the return spring (25).
