We study the binding energy and the width of the Theta(+) in nuclei, associated to the KN and K pi N components. The first one leads to negligible contributions while the second one leads to a sizeable attraction, enough to bind the Theta(+) in nuclei. Pauli blocking and binding effects on the KN decay reduce considerably the Theta(+) decay width in nuclei and medium effects associated to the K pi N component also lead to a very small width, as a consequence of which one finds separation between the bound levels considerably larger than the width of the states.
