A dispensing device for dispensing a liquid flowing through a substantially vertical tube, particularly for dispensing rain water flowing through a drainpipe wherein a sleeve has a circumferential resiliently deformable wall portion which is adjustable into two different positions, namely a first position in which the inner surface of the wall portion, possibly together with the end portion of the pipe, provides the collecting pocket, and a second position in which the inner surface is substantially conical for not collecting and discharging any liquid letting the liquid pass through the sleeve.
