Abstract
The present invention relates to a male fluid coupling to be pushed into a female coupling in order to form a fluidic coupling device with no dead volume able to transfer a fluid, and to such a device. The female coupling () is coupled to a first pipe (C) communicating with a second pipe (C) passing through the male coupling, this female coupling having an internal push-fitting surface () ending in a female end () at which the first pipe emerges, and male coupling comprises an external push-fitting surface () ending in a male end () intended to lie inside the female coupling. This second pipe is pushed into the male coupling beyond the male end and has a free end () pressed fluid tightly against the female end by return means () which, during a push-fitting operation, collaborate with guiding and retaining means () designed to guide this second pipe as it slides through the male coupling while keeping this free end against the female end so as to eliminate any dead volume between the first pipe and the male coupling, making this male coupling compatible with all kinds of corresponding female couplings.
