A ski locking device and method for securing a pair of snow skis equipped with snow brakes are provided. The ski locking device comprises a housing having a rear portion, and a lockable closure member connected to the housing. The housing and the lockable closure member are configured such that, when the ski locking device is in a closed position locking a pair of skis, with a slide surface of the first ski facing a slide surface of the second ski, the rear portion of the housing faces a first edge of the first ski and a second edge of the second ski. The lockable closure member encloses the snow brakes at a crossing point of the snow brakes.
