Ok, something like

cl = cb.ax.get_yticklabels()
cl[0].set_text('bla')
cb.ax.set_yticklabels([elem.get_text() for elem in cl])

would work for the horizontal colorbars and y replaced by x. But

cl = cb.ax.get_yticklabels()

results in a list of Text objects like Text(0,0,''). So my problem is more to get the TickLabels for vertical colorbars.

Cheers
