A spring tensioning device 100 comprises a body 102, a drum 104 rotatably mounted said body around axis 106, a cord 108 and a constant tension spring 110. The cord has a leading part 112, and a trailing part 114 which in an initial configuration is wound around the drum 104, the trailing part (Figure 6, item 114) unwinds from the drum as the drum rotates in a first direction 120 about the axis. The spring is mounted on the body and applies a near-constant resilient bias to the drum when in use, urging the drum to rotate in a second direction, opposite to the first. The spring is mounted alongside the drum, spaced in a radial direction "R" from the rotation axis of the drum.
