1. Device for testing the sealing of at least one system for insulating two mediums in a sealed manner, said test device including a casing comprising an inflatable seal configured to contact, in the inflated state, with the system and to ensure a sealing enabling the definition of a test volume between the system and the casing, a pneumatic pump and a pneumatic circuit configured, in a first step, to connect the pump to the inflatable seal such that the pump inflates the inflatable seal, and in a second step, to connect the pump to the test volume such that the pump generates in the test volume a pressure at a given value, and at least one sensor for measuring the pressure in the test volume, the pneumatic circuit being configured to ensure at least a connection of the test volume with a depression orifice of the pump, wherein the pneumatic circuit includes at least one distributor between the pump and the inflatable seal, at least one distributor between the pump and the test volume, and at least one distributor between the inflatable seal, the test volume and a draining zone, and wherein the distributor between the pump and the test volume is configured to ensure at least a connection of the test volume with the depression orifice of the pump.
