2103588 9213601 PCTABS00014 An energy absorbing device (10; 30; 50, 82) for use in a fall arresting system is described comprising a housing (16, 20; 38, 40; 52; 58; 82, 82a) for receiving webbing (12; 32; 62; 86) of a harness coupled to a person or object, the housing being adapted to be coupled to an anchor point. The webbing passes through the device and an external loop (24; 34; 74) of webbing is formed and at least two layers of webbing (12a, 12b; 32a, 32b; 62; 86) are sandwiched in a close fitting relationship in a longitudinal channel (18; 42; 60) of the device. In the event of a fall a force is applied to the object or body and the loop, which is free-running, takes up the initial force and limits the force applied to the body to a first value (F1). Once the free loop is taken up, slippage between the webbing layers and between the webbing and the surfaces of the housing creates friction which controls the maximum force (F2) applied to the body or object. Embodiments of the invention are described.
