A personal safety device (10) adapted for longitudinal movement relative to an elongate support element (50) comprises a body (11) having a bore (12) for receiving the element (50), a slipper (20) mounted on the body (11) the slipper (20) having a surface (21) oriented substantially parallel to the longitudinal axis of said bore (12), and connector (30) connected to the slipper (20) and being adapted at its other end (31) for connection to a personal safety harness. Slipper (20) is movable between first and second positions in response to sudden loading of the connector (30). In the first position, surface (21) allows free passage element (50) through the bore (12). When slipper (20) is in the second position, surface (21) clamps element (50) firmly to body (11).
