The invention claimed is: 1. Electric kettle including a power supply base comprising electrical connection means suitable for being connected to an external electrical source, and a manual control button movable between a resting position and an activation position, and a receptacle, removable from the power supply base, comprising a container suitable for containing a liquid to be heated, an electrical heating device suitable for heating the liquid in the container, and complementary electrical connection means which are suitable, when the receptacle is placed on the power supply base, for cooperating with the electrical connection means and supplying electrical power to the heating device, characterized in that the receptacle includes control means suitable for cutting the electrical power supply to the electrical heating device and which include a switch that is movable between an open position and a closed position, wherein the kettle includes transmission means suitable, when the receptacle is placed on the base, for shifting the switch from its open position to its closed position when the manual control button is shifted from its resting position to its activation position. 2. Electric kettle according to claim 1, characterized in that, when the electrical connection means of the power supply base and the complementary electrical connection means of the receptacle are in contact, the transmission means are suitable for shifting the switch into the closed position when the manual control button is shifted to the activation position. 3. Kettle according to claim 1, characterized in that the transmission means include transmission elements housed in the power supply base, movable between a resting position and an activation position in which the manual control button is in the activation position, and complementary transmission elements housed in the receptacle, movable between a resting position and an activation position in which the transmission elements are in the activation position and the switch is in the closed position, with the receptacle being connected to the power supply base. 4. Kettle according to claim 3, characterized in that the transmission elements include a lever pivotably mounted with respect to the power supply base of which a first end is attached to the manual control button, and the second end is suitable for driving the complementary transmission elements towards their activation position. 5. Kettle according to claim 4, characterized in that the transmission elements include at least one plunger attached to the second end of the lever, slidably mounted in the power supply base, and suitable for passing through at least one opening provided in a receiving wall of the power supply base on which the receptacle is resting, for coming into contact with the complementary transmission elements and driving them into their activation position when the manual control button is in the activation position. 6. Kettle according to claim 3, characterized in that the complementary transmission elements include at least one sliding element slidably mounted in the receptacle and suitable for passing through at least one orifice provided in the base wall of the receptacle and for coming into contact with the transmission elements and driving the switch towards its closed position when the manual control button is in the activation position. 7. Kettle according to claim 6, characterized in that a pivoting arm is mounted integrally with the switch and is suitable for coming into contact with all of the sliding elements. 8. Kettle according to claim 6, characterized in that the base wall of the receptacle includes an annular shoulder projecting from the receptacle and suitable for resting on the power supply base, and a central recess in which all of the orifices are provided. 9. Kettle according to claim 1, characterized in that the manual control button is constantly urged towards its resting position by a spring. 10. Kettle according to claim 1, characterized in that the switch is bistable. 11. Kettle according to claim 1, characterized in that the transmission means are designed so as to shift the switch into closed position when the manual control button is in the activation position, regardless of the angular position of the receptacle on the power supply base. 12. Kettle according to claim 11, characterized in that the transmission means are cylindrically symmetrical and coaxial to the electrical connection means and to the complementary electrical connection means. 13. Kettle according to claim 12, wherein the transmission means include transmission elements housed in the power supply base, movable between a resting position and an activation position in which the manual control button is in the activation position, and complementary transmission elements housed in the receptacle, movable between a resting position and an activation position in which the transmission elements are in the activation position and the switch is in the closed position, with the receptacle being connected to the power supply base, wherein the transmission elements include a lever pivotably mounted with respect to the power supply base, of which a first end is attached to the manual control button, and the second end is suitable for driving the complementary transmission elements towards their activation position, wherein the transmission elements include at least one plunger attached to the second end of the lever, slidably mounted in the power supply base, and suitable for passing through at least one opening provided in a receiving wall of the power supply base on which the receptacle is resting, for coming into contact with the complementary transmission elements and driving them into their activation position when the manual control button is in the activation position, and wherein the complementary transmission elements include at least one sliding element slidably mounted in the receptacle and suitable for passing through at least one orifice provided in the base wall of the receptacle and for coming into contact with the transmission elements and driving the switch towards its closed position when the manual control button is in the activation position, characterized in that, the transmission means are radially arranged outside the electrical connection means and the complementary electrical connection means, wherein all of the arc-shaped openings and orifices are radially and angularly distributed so that, regardless of the angular position of the receptacle, at least one angular cross-section portion of an opening is opposite an orifice. 14.
