A device for winding a strap or strip of material for maneuvering a shutter, roller blind or equivalent device comprising a member for winding and tensioning the strap disposed inside a box formed by two shells each including at least one edging extending in a direction substantially perpendicular to a principal web of each shell. The edgings are adapted to be brought into mutual engagement by a relative translation in a direction substantially parallel to the respective principal webs of the shells, in a configuration where an edging of a first shell is covered by an edging of a second shell.
