Based on the ideas of Tannaka-KreΔ± ˘n reconstruction, we present a categorical construction that assigns to any cleft Hopf algebra inclusion K … H a coquasibialgebra having K\* as a Hopf subalgebra. As a special case, the construction gives an intrinsic connection between the bismash product K#Q and
