1. A quick connection for removably joining two pipes through which a fluid flows, the connection comprising; a male element and a female element adapted to fit axially relative to one another, the female element including a body in which a lock is slidably mounted, the lock having at least one opening for the fit of the male element, a wall defining the at least one opening having at least one first element in relief adapted to cooperate with a corresponding second element in relief of the male element in order to retain the male and female elements in fitted configuration, the lock including a first part on which may be exerted, from outside the body, a force of displacement, and a second part, movable with respect to the first part and bearing the element in relief, and a safety member mounted within the female member and being adapted to block the first part against a force of displacement, without preventing a displacement of the element in relief with respect to the first part.
2. The connection of claim 1, for elastically urging the safety member towards a position in which it blocks the first part.
3. The connection of claim 1, wherein the lock is installed in a first housing in which it may slide between outer and inner positions, elastic means for urging the lock into the outer position and against a force of displacement in a direction substantially perpendicular to the direction of fit of the male and female elements.
4. The connection of claim 3, including a stop movable within the first housing so as to be adapted to abut a portion of the second part of the lock.
5. The connection of claim 1, wherein the lock is mounted in a first housing in which its first part may slide against a force of an elastic means for urging the lock against a force of displacement, in a direction substantially perpendicular to the direction of fit of the male and female elements, and the second part is slidable in said first housing in a direction substantially parallel to the direction of fit.
6. The connection of claim 1, wherein the first part defines a second housing in which the second part is disposed, said second housing being open opposite the actuation surface of the first part.
7. The connection of claim 1, wherein said safety member is movable in a direction parallel to the direction of fit of the male and female elements between a first position where the safety member blocks the first part and a second position where the safety member does not oppose the movement of the first part under the effect of an effort of displacement.
8. The connection of claim 7, wherein said safety member is adapted to be displaced from the first towards the second position by a force applied to urge the male element further within the female element.
9. The connection of claim 8, wherein said safety member is adapted to move from the first to the second position by a force applied to urge the male element further within the female element from a configuration where the male and female elements are initially coupled.
10. The connection of claim 8, wherein the safety member is provided with a surface adapted to receive in abutment the element in relief of the male element for the transmission of an effort of displacement of said safety member from the first towards the second position.
11. The connection of claim 7, wherein said safety member is provided with a surface forming a stop to the displacement of the lock by a force of an elastic means.
12. The connection of claim 1, wherein said element in relief of the second part is in one piece with the second part.

17. 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 elements in relief formed respectively on the male element of a wall defining an opening in a lock mounted to slide in a body of the female element and in which the male element is introduced, the process including the steps of:
exerting a force urging the male and female elements toward each other while coupled by pushing, against an elastic effort, a member which blocks a part of the lock that is accessible from outside the body;
exerting on a part of the lock accessible from outside the body, a force to the body; and
withdrawing the male element from the female element by a movement in the direction of fit of the elements.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A rotor for an electric motor, comprising:
a metal core,
a plurality of electrical conductors arranged on the metal core, and
a metallic corrosion protection layer enveloping the metal core and the plurality of conductors, the corrosion protection layer being laid as a solid body around the metal core and the conductors and fastened at least to the metal core,
wherein the corrosion protection layer is at least a part of a hot-pressing containment for isostatic pressing of the conductors in the metal core, and
wherein, between the metal core and the corrosion protection layer, there is a metallic interlayer which is diffused by hot isostatic pressing into the metal core and the corrosion protection layer and holds them together.
2. The rotor as claimed in claim 1, wherein the corrosion protection layer is connected to at least the metal core by shrinkage.
3. The rotor as claimed in claim 1, wherein the corrosion protection layer is connected to at least the metal core by hot isostatic pressing.
4. The rotor as claimed in claim 1, wherein the corrosion protection layer is welded to region of the metal core on one edge.
5. The rotor as claimed in claim 4, wherein the region comprises, in the direction toward the corrosion protection layer, a metallic buffer layer to which the corrosion protection layer is welded and which differs in its composition from the underlying substrate of the metal core.
6. The rotor as claimed in claim 1, wherein the corrosion protection layer is a cylindrical metal tube which is respectively connected to the metal core at its ends.
7. The rotor as claimed in claim 6, wherein the ends are respectively connected to a termination ring which holds the conductors axially in position on the metal core.
8. The rotor as claimed in claim 6, wherein the ends are respectively connected gas-tightly to an extension of the metal core extending radially outward.
9. The rotor as claimed in claim 8, wherein the extension is a termination ring which holds the conductors axially in position on the metal core.
