The invention concerns a positive Luer-lock connector to connect all standardised negative Luer-lock connectors with a Luer taper (27), a rear shaft (23) joining the Luer taper (27) and a lock's thread (19). Such detachable connectors are available with various designs. Especially when administering toxic and generally environmentally hazardous media, like for example cytostatic agents, it is desirable to prevent any disconnection of the Luer-lock connection, so that neither patients, nor personnel would get into contact with it. According to the invention this is achieved by that the connector has cogs (15) effectively joined with the lock's thread (19) and that a capping sleeve (11) is placed undetachably from and rotatably on the shaft, the capping sleeve having on its inside counter- cogs (22) matching the cogs (15), while the cogs (15) and counter-cogs (22) are so constructed, that in a first direction of rotation they engage one another in an arresting manner so that to lock the Luer-lock connection of the capping sleeve (11) on the shaft, in a second direction of rotation, that is opposing the first direction of rotation, they slide off one another in a free-wheeling manner.
