A shroud 9 for the drive chain of a roller blind. The drive chain has a series of balls mounted on a cord or wire and is in the form of a pair of leg members forming a loop. The shroud comprises an elongate body 10 having opposed open ends 11, 12 with an internal passageway 13 extending therebetween. The body has an enclosed volume extending between the open ends. A longitudinal internal baffle 14 extends between the open ends, segmenting the internal passageway into two longitudinal channels 15, 16, each channel extending between the open ends and dimensioned to slidably receive one of the pair of chain leg members therethrough. The baffle has a longitudinal slot 17 extending along its length, where the slot is dimensioned to permit the receipt of the cord or wire of the drive chain, and is dimensioned to preclude the passage of the balls of the drive chain therethrough. In a second aspect, a shroud having an elongate body dimensioned to receive a pair of chain leg members that extend through an open end of the elongate body to be secured to a chain retainer.
