A lifeline arrangement comprising: a lifeline 210; a tensioner (100, Fig.1) for the lifeline, the tensioner including: a housing; a pulley 102 that, is disposed within the housing, is connected to a drive shaft (108, Fig.1), accommodates a portion of the lifeline within a circumferential channel 104, and that rotates via rotation of the drive shaft relative to the housing about a first axis; a lifeline locking element 156 including a lifeline engagement portion 161 and an anchor portion 159, wherein the lifeline engagement portion has an engaged configuration in which it engages a portion of the lifeline within the circumferential channel to permit displacement in a tensioning direction but prevents displacement in a loosening direction, and a release configuration in which it is spaced from the lifeline; and a connector (216, Fig.11) connected to the anchor portion; and wherein an operating wheel 200 is connected to the drive shaft; and/or a tension indicator (500, Fig.16) is located between the connector and the anchor portion to senses a tensile force applied to the lifeline and indicates if the sensed tensile force is within a pre-determined range; and/or a distal end of the lifeline includes a swivel (528, Fig. 17).
