A drainage circuit surrounding a hydraulic circuit, such as a circuit for distributing drinking water on an aircraft, includes an element around one enlarged portion (right connector, T, Y connector, etc) of the hydraulic circuit, namely a draining unit (20) formed of two half shells (24, 26) and tubular joining pieces (28). Imperviousness between the two half shells and between the half shells and the joining pieces is ensured by projecting portions (36, 38) which penetrate into a humidity-repellent stabilized gel (40) placed inside receptacles (42, 44). In addition, clipping members (48, 50) are provided on the half shells.
