An assisting suspension arrangement for suspending a monitoring device, the suspension arrangement comprising: a hook member (20, 50, 60, 70); a blocking member (22, 52, 62, 72); and a resilient member; wherein the suspension arrangement is configured to adopt an open state, in which the hook member (20, 50, 60, 70) is arranged to enable engagement with a suspension element for suspending a monitoring device, and a closed state, in which the blocking member (22, 52, 62, 72) is arranged to prevent disengagement of the suspension element from the hook member (20, 50, 60, 70); wherein the open state and the closed state are enabled by the hook member (20, 50, 60, 70) being movable in relation to the blocking member (22, 52, 62, 72); wherein the resilient member is arranged to bias the suspension arrangement toward the closed state; wherein the suspension arrangement is configured such that when said monitoring device is suspended by said suspension arrangement, the hook member (20, 50, 60, 70) is adapted to carry the weight of said monitoring device and thereby to transfer the load to the resilient member and to move toward the open state of the suspension arrangement; and wherein the suspension arrangement is configured such that when the load of the weight of said monitoring device is released from the hook member (20, 50, 60, 70), the resilient member is adapted to move the hook member (20, 50, 60, 70) toward the closed state of the suspension arrangement, characterized in that the hook member (20, 50, 60, 70) is provided with a slot (23, 53, 63) being arranged to receive and contain said suspension element; in that the slot (23, 53, 63) comprises an entrance portion (23a, 53a, 63a), arranged to receive said suspension element from outside the hook member (20, 50, 60, 70), and an engagement portion (23b, 53b, 63b), arranged to contain said suspension element; in that the slot (23, 53, 63) is arranged such that when said monitoring device is suspended by the suspension arrangement, said suspension element is forced away from the entrance portion (23a, 53a, 63a) into the engagement portion (23b, 53b, 63b) of the slot; and in that the blocking member (22, 52, 62) comprises an elongated portion extending along and adjacent to an outer surface of the hook member (20, 50, 60) and transverse to a side of the slot (23, 53, 63) of the hook member (20, 50, 60) such that the blocking member (22, 52, 62) prevents a suspension element contained in the engagement portion (23b, 53b, 63b) from exiting through the entrance portion. a hook member (20, 50, 60, 70); a blocking member (22, 52, 62, 72); and a resilient member; wherein the suspension arrangement is configured to adopt an open state, in which the hook member (20, 50, 60, 70) is arranged to enable engagement with a suspension element for suspending a monitoring device, and a closed state, in which the blocking member (22, 52, 62, 72) is arranged to prevent disengagement of the suspension element from the hook member (20, 50, 60, 70); wherein the open state and the closed state are enabled by the hook member (20, 50, 60, 70) being movable in relation to the blocking member (22, 52, 62, 72); wherein the resilient member is arranged to bias the suspension arrangement toward the closed state; wherein the suspension arrangement is configured such that when said monitoring device is suspended by said suspension arrangement, the hook member (20, 50, 60, 70) is adapted to carry the weight of said monitoring device and thereby to transfer the load to the resilient member and to move toward the open state of the suspension arrangement; and wherein the suspension arrangement is configured such that when the load of the weight of said monitoring device is released from the hook member (20, 50, 60, 70), the resilient member is adapted to move the hook member (20, 50, 60, 70) toward the closed state of the suspension arrangement, characterized in that the hook member (20, 50, 60, 70) is provided with a slot (23, 53, 63) being arranged to receive and contain said suspension element; in that the slot (23, 53, 63) comprises an entrance portion (23a, 53a, 63a), arranged to receive said suspension element from outside the hook member (20, 50, 60, 70), and an engagement portion (23b, 53b, 63b), arranged to contain said suspension element; in that the slot (23, 53, 63) is arranged such that when said monitoring device is suspended by the suspension arrangement, said suspension element is forced away from the entrance portion (23a, 53a, 63a) into the engagement portion (23b, 53b, 63b) of the slot; and in that the blocking member (22, 52, 62) comprises an elongated portion extending along and adjacent to an outer surface of the hook member (20, 50, 60) and transverse to a side of the slot (23, 53, 63) of the hook member (20, 50, 60) such that the blocking member (22, 52, 62) prevents a suspension element contained in the engagement portion (23b, 53b, 63b) from exiting through the entrance portion.
