The invention relates to a tensioning device 10 installable in a temporary horizontal lifeline system for the tensioning thereof. The tensioning device 10 comprises a pulley comprising a pulley wheel 14 connected to a drive spindle 28, said lifeline passing, in use, around said pulley wheel 14. An integral handle assembly 18 is further connected to the drive spindle 28; the handle assembly 18 being moveable between a first, disengaged position (Fig 5-6) in which rotation of the handle 18 assembly does not cause rotation of the drive spindle 28 and a second, engaged position (Fig 7-8) in which rotation of the handle 18 assembly rotates the drive spindle 28. Rotation of the drive spindle 28 serving, in use, to rotate the pulley 14 to move the lifeline in a second direction relative to a braking member 16 which is configured to engage, in use, with a part of a lifeline - thereby tensioning the lifeline. The provision of an integral handle 18 being such that no additional tools is required for tensioning operation.
