1. A device for transferring fluid comprising: a fluid reservoir in fluid communication with the male-connector ferrule which is made conical to create, when introduced into the corresponding female nozzle, the friction coupling, a release component able to move relative to the male connector, between the first tip position proximal with respect to the reservoir for fluid and a second position displaced from the first position to the distal end of the male -Connector ferrule, to release it from a friction coupling, iuderzhivayuschee means able to hold the covering nozzle after its liberation from the frictional coupling disconnects the component when it is moved to its second polozheniyu.2. An apparatus for transferring a fluid, connected with a female head, and comprising: a fluid reservoir in fluid communication with the male tip-connector, which is inserted into the female attachment to form a friction pairing, a release component able to move relative to the male tip-connector between a first position proximal with respect to the reservoir for fluid and a second position displaced from the first position to the distal end of the male Nakhon echnika-connector, to release it from a friction coupling, iuderzhivayuschee means able to hold the covering nozzle after its liberation from the frictional coupling disconnects the component when it is moved to its second polozheniyu.3. A device according to
