An enclosure comprises at least first and second components 2 & 4 connected to one another, the first and second components at least partially defining an internal space 6 and each having a hinged connection 3 & 5, wherein the first and second components are moveable with respect to one another between at least two configurations, without being disconnected; in a first configuration (figure 1 & 2), the enclosure is openable about the hinged connections and thereby the internal space is accessible by a user; and in a second configuration (figure 3 & 4) , the enclosure is not openable about the hinged connections and the internal space is inaccessible by the user. The first and second components may be rotatable with respect to one another to move between the first and second configurations. The first and second components may be guided in their relative rotation by a split ring 7 and corresponding groove 8 for receiving the split ring. The enclosure may be used in particular for storing jewellery or pills.
