This connection comprises two elements, male and female, adapted to fit axially in each other, the body of the female element being equipped with a lock mounted to slide and pierced with at least one opening for the fit of the male element. The wall of this opening is equipped with at least one element in relief adapted to cooperate with a corresponding element in relief of the male element in order to retain these elements in fitted configuration. The lock is in two parts and comprises a first part on which may be exerted, from outside the body, an effort of displacement, as well as a second part mobile with respect to the first part and bearing the aforementioned element in relief. A safety member is adapted to block the first part against the effort of displacement, without preventing the displacement of the element in relief with respect to the first part of the connection. The male and female elements may be uncoupled by exerting an additional effort of fit, then by exerting an effort of penetration of a part of the lock in the body and by withdrawing the male element from the female element.

What is claimed is: 1. A quick connection for removably joining two pipes through which a fluid flows, said connection comprising a male element and a female element adapted to fit axially in each other, a body of said female element being equipped with a lock mounted to slide in said body and having at least one opening into which said male element is received, said lock being in two parts and including a first part on which may be exerted, from outside said body, a force of displacement, and a second part movable with respect to said first part, at least one ball element mounted within at least one orifice through a wall of said second part, said at least one ball element cooperates with a groove disposed on said male element to retain said male and female elements in fitted configuration, and a safety portion of said second part being adapted to block said first part against said force of displacement without preventing a displacement of said at least one ball element with respect to said first part. 2. The connection of claim 1, further comprising a means for elastically loading said safety portion of said second part toward a position in which said safety portion blocks said first part. 3. The connection of claim 1, wherein said lock is in a housing in which said first part slides, against an elastic return means, in a direction substantially perpendicular to a direction of fit of said male and female elements, while said second part slides in said housing in a direction substantially parallel to the direction of fit. 4. The connection of claim 1, wherein said first part defines a housing in which said second part is disposed, said housing being open opposite an outer actuation surface of said first part. 5. The connection of claim 1, wherein said safety portion is moveable in a direction parallel to a direction of fit of said male and female elements between a first position wherein said safety portion blocks said first part and a second position wherein said safety portion does not oppose the movement of said at least one ball element under the effect of the force of displacement. 6. The connection of claim 5, wherein said safety portion is adapted to be displaced from a first toward a second position by said male element. 7. The connection of claim 6, wherein said safety portion is adapted to pass from the first to the second position under an effect of an additional fit of said male element in said female element, from a configuration where said elements are initially coupled. 8. The connection of claim 6, wherein the safety portion is provided with a surface adapted to abut a portion of said male element for a transmission of a force of displacement of said safety portion from the first toward the second position thereof. 9. The connection of claim 1, wherein said at least one ball element is movably mounted on said second part. 10. The connection of claim 9, wherein said second part is a ring provided with a bore traversing it radially and in which said at least one ball element is mounted, said at least one ball element being able to be blocked by projecting radially in the central opening of said ring or be driven radially outside said opening, as a function of the position of said second part with respect to said first part. 11. The connection of claim 1, wherein said second part is in one piece with said safety portion. 12. A process of uncoupling male and female elements of a quick connection previously fitted in each other and retained in coupled configuration by the cooperation of a groove and at least one ball element formed respectively on the male element and in a wall of an opening in a lock mounted to slide in the body of the female element and in which the male element is seated, and the lock being accessible from outside the body of the female element and being blocked from movement into the body of the female element when the male and female elements are coupled with one another by a blocking member, the process comprising: exerting a force urging the male and female elements toward each other which force is directed against the blocking member so that the blocking member is urged, against an elastic force, to a position so as not to block movement of the lock within the body of the female element; exerting on a part of the lock accessible from outside the body, an effort of penetration forcing the lock into the body of the female element; and thereafter withdrawing the male element from the female element by a movement in a direction opposite a direction of fit of the male element and the female element.
