One studies the flow prolongation of projectable vector fields with respect to a bundle functor of order on the category of fibered manifolds. As a result, one constructs an operator transforming connections on a fibered manifold into connections on an arbitrary vertical bundle over . It is deduced that this operator is the only natural one of finite order and one presents a condition on vertical bundles over under which every natural operator in question has finite order.
