ABSTRACT OF THE DISCLOSURE A catheter connecting head with at least one duct in a base member for the connection of an infusion system, such as a catheter or the like and for the introduction of a puncture cannula, is provided with a closure member mounted for movement between a first position opening the cannula introduction duct and a second posi- tion blocking said duct. The connecting head is provided with a device for retaining the closure member in the first position until the puncture cannula is withdrawn after which the closure element is automatically shifted into its second position, Once the closure member is in its second position blocking the cannula insertion duct, a locking arrange- ment retains the closure member in this position so that reintroduction of a puncture cannula into said insertion duct is not possible. In accordance with preferred embodiments, the closure member can be constructed as a lever member pivotally mounted to the base member or as a disc mounted upon the base member in a rotatable manner.
