The production of a quick connection device including a metal journal that fits in a complementary manner into a connector is performed by a process including the following steps: a metal tube is extruded to form a blank of the journal extending longitudinally from a large end to a small end along a first cylindrical portion; from the first cylindrical portion, the blank narrows along a conical portion to a second cylindrical portion. The wall of the tubular blank has a thickness that is substantially constant in all three portions.
