<p>The connector (12) has cogs (15) joined with a thread of a lock. A capping sleeve (11) is undetachably and rotatably placed on a shaft. The capping sleeve has counter-cogs (22) matching the cogs. The cogs and the counter-cogs are constructed such that the cogs and the counter-cogs engage one another in an arresting manner to lock a luer-lock connection of the capping sleeve on the shaft in a rotation direction, and slide off one another in a freewheeling manner in another rotation direction. The cogs and the counter-cogs have oppositely directed engagement surfaces.</p> |
