Patent ID: 8720254

Claim:
A device for detecting micro-leaks in a wall, including a capsule ( 11 ) covering and surrounding a micro-leak ( 12 ) by a peripheral face ( 28 ), a device for detecting a chemical species having leaked, a pipe ( 14 ) connecting a main face ( 27 ) of the capsule and the detection device, and a pump ( 16 ) circulating gas through the pipe, wherein the capsule ( 11 ) includes the main face ( 27 ), the peripheral face ( 28 ) and ribs ( 29 ), where the main face is essentially flat, the peripheral face is essentially perpendicular to the main face and has openings ( 32 ), and the ribs ( 29 ) are located under the main face, diverging from one another in a radial direction, from a location ( 30 ) where the pipe ( 14 ) emerges from the capsule in the peripheral face ( 28 ), delimiting channels ( 31 ) leading respectively to the openings ( 32 ) of the peripheral face.
