Abstract: The invention relates to a device for loading a patient connector for peritoneal dialysis with a closure plug. To permit an arbitrary number of disconnection/connection procedures with patient connectors that insert a sterile closure plug into the patient's abdominal connector during disconnection, a device for loading a patient connector for peritoneal dialysis with a closure plug is suggested, said device consisting of a housing containing a closure plug and of means for transferring the closure plug out of the device and into a patient connector. This permits loading, under sterile conditions, of a patient connector whose closure plug has already been used with a new closure plug. By loading a new closure plug, the push-button with which the closure plug is inserted is returned to its starting position, so that the patient connector is again available for a connection/disconnection procedure.
