The present invention relates to a device for forming drops for installations for watering crops with an adjustable low flowrate. This device includes a tip (2), on the periphery of which a helicoid groove (6) forming a channel is produced, the said tip being fitted by self-tapping screwing into the dispensing conduit (1) so as to allow adjustment of the fluid flowrate by altering the head loss of the fluid flow. This alteration of the head loss is obtained by varying the working length (l) of the flow channel. <IMAGE>
