Compare on the fly your current values and return false if :

$(function() {
    $( "#slider-range" ).slider({
        range: true,
        min: 1,
        max: 10,
        values: [ 3, 5 ],
        slide: function(event, ui) {
            if (ui.values[0] >= ui.values[1] ) {
                return false;
            }
        }
    });
});
