Patent ID: 8876733

Claim:
A male fluidic coupling configured to be press fitted into a female fluidic coupling connected to a first conduit intended to communicate with a second conduit passing through the male coupling, in order to form a fluidic coupling device able to transfer a fluid, such as microsamples that are to be collected or to be injected, the female coupling comprising an internal press fitting surface terminating in a female radial end at which said first conduit emerges, the male coupling comprising an external press fitting surface terminating in a first male radial end intended to be located inside the female coupling, wherein said second conduit is formed by a flexible tube which is pushed into the male coupling axially beyond said first male end and which terminates in a free end, said free end having a symmetry of revolution and being able to be pressed in a leaktight manner against said female end by return means which are integrated in the male coupling, said return means cooperating, during the press fitting, with guiding and retaining means provided in the male coupling in order to guide said tube in an axial sliding movement through the male coupling by bringing said free end close to said first male end while keeping said free end against said female end, so as to eliminate any dead volume between the first conduit and the male coupling.
