Abstract: This single-use drip-feed device comprises, in this order, mutually joined together and communicating, a connector which can be linked to a feed tube supplying a drip-feed liquid, a narrow linking tube and a needle having two diametrically opposite flexible tabs for handling, and with the aim of rendering harmless the needle after use, has a tubular cover fitted in a freely sliding manner over the narrow tube, with, beginning at the extremity towards the needle, two longitudinal slots diametrically opposite each other into which the tabs of the needle are inserted so as to cover completely the point of the latter; the cover is made of a material which cannot be pierced by the needle but at the same time is sufficiently elastic to permit insertion of the tabs into the slots.
