The present invention relates to a multi-part safety closure for a hot-water bottle. The multi-part safety closure for a hot-water bottle comprises: at least one closure part (4) having an external screw thread (12) for screwing into an internal screw thread of a hot-water bottle and having a first force transmission element (6) for transmitting momentum for screwing the closure part (4) into an internal screw thread of a hot-water bottle (14) for sealing said bottle (14) in a water-tight manner and for unscrewing the closure part (4) from an internal screw thread (17) of a hot-water bottle (14); and a manual actuating element (2) having a second force transmission element (8) for introducing into the closure part (4) the momentum required to screw and unscrew the closure part (4) into and from an internal screw thread (17) of a hot-water bottle (14). According to the invention, the first force transmission element (6) and the second force transmission element (8) are designed to correspond in such a way that the closure part (4) and the hand actuating element (2) can be releasably coupled to one another, forming an operative connection.
