A gland assembly includes a gland body (3) and a cap nut (5) connected by screw threads (25). A cable holding device (11) is received within the cap nut (5) and has a plurality of fingers (19) configured to apply a gripping force to a cable (7) extending through the gland assembly in response to a torque applied to the cap nut (5). The fingers (19) are configured to increase the gripping force on the cable (7) in response to a linear force applied to the elongate member.
