An electronic smoking device (210, 310, 410) has two portions (12, 13) wherein one of the portions (12, 13) comprises a cavity (240, 340, 440) for a liquid reservoir (234, 334, 434). The portions (12, 13) can be moved with respect to each other, by a movement and a respective counter movement, at least between an insertion configuration and a closed cavity configuration. In the insertion configuration a liquid reservoir (234, 334, 434) can be inserted into the cavity (340, 440). In a closed cavity configuration, the cavity (240, 340, 440) is closed by the other portion and a liquid reservoir opening element (70) of said one or the other portion opens the housed liquid reservoir (234, 334, 434).
