Abstract

A medical injection device has an injection unit and an anti-rotation device. Said anti-rotation device is non-rotationally connected to a port and connection portion of the injection device so as to surround the outside thereof in the manner of a sleeve. As a result, an intuitively usable and operationally safe injection device is obtained. When a protective cap for an injection cannula of the injection unit is being removed from the port and connection portion, an unwanted rotation of the port and connection portion relative to the container about components of a plug-in connection arranged therebetween is safely prevented.
