A ladder securing device configured to attach to a rung(s) of an extension ladder using a pair of clamps and including a pair of pivotal clamp arms for securing to a desired structure or surface to which the ladder is to be secured. The device includes a pulley connected to a rope, wherein the rope is eased off and pulled to pivotally move the clamp arms to secure to the structure. The clamp arms are connected to pivotal blocks and a plurality of torsional springs provide smooth and slow movement of the clamp arms. For providing additional support, a connecting rod connects the clamp arms and a fastener secures the clamp arms. The device allows a user to securely ascend and descend on the ladder without any additional support and thus prevents serious injury due to unstable ladders which ultimately can lead to falls.
