We extend Tulczyjew's geometrical formulation of skewsymmetric tensor gauge fields as connections on generalized principal fibrebundles to the category of supermanifolds. Given a smooth d-dimensional manifold M and a k -form field on it we construct a suitable supersmooth generalized principal fibrebundle P over a (d,2)-dimensional supermanifold M such that BRS symmetries of the theory have a natural geometrical interpretation.
