1. An implantable chamber (100), having an inner space defined by two semi-permeable membranes sealed together at their periphery,
for diffusing at least one substance of interest, characterized in that it comprises:
an upper washer (120) and a bottom washer (110) configured to be oppositely placed on a side and on another side of two semi-permeable membranes (141, 142),
wherein the two semi-permeable membranes are superposed in between the upper and the bottom washers (120, 110), wherein the upper washer (120) is tightly clipped to the bottom washer (110), wherein the chamber further comprises at least one intermediate washer (130), provided between both membranes, in a plane parallel to the upper and bottom washers' planes and delimiting two superposed half spaces (S1, S2), the upper and bottom washers (120, 110) incorporating the intermediate washer (130) therebetween upon clipping,
and wherein:
the bottom washer (110) comprises at least two blades (111, 112) extending in planes orthogonal to the upper and bottom washers' planes,
the upper washer (120) comprises housings (126) for receiving free ends of the blades (111, 112) in order to clip the upper washer with the bottom washer, and
the intermediate washer (130) and the membranes (141, 142) comprise first openings (131, 143) arranged to be crossed by the blades.
 
12. A kit connector comprising:
an upper washer (120) and a bottom washer (110) that can be tightly clipped to each other wherein the bottom washer (110) comprises at least two blades (111, 112) extending in planes orthogonal to the bottom washer (110) plane, wherein the upper washer (120) comprises housings (126) for receiving free ends of the blades (111, 112) and wherein each of the blades (111, 112) comprise, at their free end, a through-hole (114) adapted to be crossed by a pin (160) in order to tightly clip the upper washer (120) with the bottom washer (110), and tight clipping is thus performed by the pin (160) extending across the holes (114) in the free ends of the blades (111, 112), the upper washer (120) and bottom washer (110) being in parallel planes after clipping;
at least one intermediate washer (130), incorporated between the upper and the bottom washers, in a plane parallel to the upper and bottom washers' planes;
optionally sealing components (150) and
a pin (160), that can extend through the through-holes (114) to tightly clip the two washers (110, 120).
