Tension alert device is attached between opposing ends of a securing membe r attached to a load bed to secure a load thereupon. The device has a strip wi th a curved portion, which is resiliently movable towards a proximity actuation means disposed on a wall in device. When tension in securing member decreases, proximity of curved portion relative wall decreases. When curved portion enters a proximity actuation state relative first wall corresponding to a low tension state where tension is below a tension threshold level, a proximity sensor actuates a signaling device which alerts a user.
