I just fund this in "stats" ;-)

    threshold(a, threshmin=None, threshmax=None, newval=0)
        Like numpy.clip() except that values <threshmid or >threshmax 
are replaced
        by newval instead of by threshmin/threshmax (respectively).
        Returns: a, with values <threshmin or >threshmax replaced with 
newval
