A swivel device comprising inner and outer mutually rotatable swivel members (2, 3) having respective inner fluid paths (10-12 resp. 13-15) communicating with each other through one or more associated annular spaces (7-9) at the interface between the swivel members (2, 3), the annular spaces being sealed from each other by means of sealing means (18, 19). The swivel members (2, 3) are formed as an outer female member (2) and an inner male member (3), respectively, so that the male member can be introduced axially into a cooperating female member to an operative working position, or withdrawn from the female member when disconnecting the swivel members (2, 3). The sealing means (18, 19) between the annular spaces (7-9) are arranged to be activated for active sealing function in the operative working position, and to be relieved in case of mutual disconnection of the swivel members (2, 3).
