1. A device for carrying out a test on a fluid circuit of an aircraft comprising: a test unit comprising: at the inlet, a plurality of means of connection to a pressurized gas supply connected to means for regulating the pressure of the gas provided by the supply as a function of the test to be carried out;at least one inlet connector adapted to compressed air;at least one inlet connector adapted to a pressurized gas stored in a bottle; and,at the outlet, at least first and second connection means connected to the means for regulating the pressure of the gas, wherein the at least first and second connection means have different dimensions tailored to a range of pressures or a given pressure,a plurality of families of connection means, each family being adapted to a pressure range or a given pressure, wherein at least one family comprises a safety valve for maintaining the pressure delivered to the fluid circuit to be tested under predetermined threshold, said safety valve being sandwiched between a control valve and one or more of the connection means of the corresponding family, andwherein at least one family comprises, at an outlet of the control valve, a feed pipe supplying one or more of the connections means of the corresponding family and a conduit comprising a valve and a safety valve in series. 2. The device according to claim 1, further comprising at least one outlet hose to connect the connection means to a connection means provided in the area of the fluid circuit to be tested, said outlet hose having, at each end respectively, first and second connectors identical to one another and identical to the connection means of the test unit and to the connection means provided in the area of the fluid circuit to be tested. 3. The device according to claim 1, wherein, for at least one family, a safety valve is arranged in series with a valve connected at the outlet of a control valve, wherein the outlet of the control valve is connected to one or more of the connection means of the considered family. 4. The device according to claim 1, further comprising a three-way valve to select the inlet connection means for connecting to the regulation means. 5. The device according to claim 4, further comprising a pressure-reducing valve sandwiched between the inlet connector adapted to a pressurized gas stored in a bottle and the three-way valve. 6. The device according to claim 1, wherein the test unit is removably connected to a carriage. 7. The device according to claim 6, wherein the carriage comprises a chassis and a tiller adapted to pivot about a horizontal axis between a substantially vertical raised position and a horizontal position. 8. The device according to claim 7, wherein the carriage comprises a brake system configured to be activated when the tiller is in the raised position. 9. The device according to claim 7, wherein the carriage comprises locking means of the tiller in the raised position. 10. The device according to claim 9, wherein the locking means comprise a cross pin with, an horizontal axis, and, a vertical axis, arranged between first and second parallel plates whose upper end is configured to be housed in a housing arranged in a plate affixed to the tiller, the horizontal axis being housed in oblong holes housed in the parallel plates and oriented vertically so that the cross pin is configured to move vertically in translation, and return means tending to maintain the cross pin in the upper position.
