I claim:
1. A device for fastening ski boots, comprising a fluid reservoir, a pumping means connected to said reservoir for pumping fluid out of said reservoir, a selector assembly having an inlet chamber connected to said pumping means for receiving fluid pumped by said pumping means and further connected to said reservoir for returning fluid into said reservoir, valve means associated to said pumping means for allowing feeding of fluid from said reservoir toward said inlet chamber and preventing fluid from passing through said pumping means toward said reservoir, valve means between said selector assembly and said reservoir for controlling return of fluid from said selector assembly to said reservoir, a plurality of fluid-operated driving members arranged on a portion of said ski boot and having means for fastening said portion with another portion of said ski boot, control conduits each connecting one of said driving members with said selector assembly, and means in said selector assembly for selectively connecting at least one of said control conduits with said inlet chamber to operate at least one of said driving members and fastening means.
