Portions of a sound and thermic insulation mattress are modified so as to retain the water imperviousness of the mattress and its insulation characteristics when it is secured to a support. The mattress is provided with an opening therein and a foam insert arranged in the opening and provided with an orifice. The insert is held in the opening by an adhesive strip which is glued to the foam insert and the mattress.

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.
