The invention claimed is: 1. A modular rotor blade for a wind turbine, comprising at least a first module and a second module, wherein the first and second modules are adapted to be rigidly fixed to each other by a connection arrangement, the connection arrangement comprising a connector rod bonded to at least one receptacle adapted to receive the connector rod, the connector rod and the at least one receptacle forming a sealing flange, wherein the connector rod and the at least one receptacle have rectangular cross sections, and wherein a permanent bonding joint defined between the first and second modules comprises a substantially uniform bond line inducing a substantially uniform load distribution between the connector rod and the at least one receptacle. 2. The modular rotor blade according to claim 1, wherein the connector rod is disposed at the first module. 3. The modular rotor blade according to claim 1, wherein the connector rod is disposed at the second module. 4. The modular rotor blade according to claim 1, wherein the receptacle is disposed at the first module. 5. The modular rotor blade according to claim 1, wherein the receptacle is disposed at the second module. 6. The modular rotor blade according to claim 1, wherein each module has essentially the same longitudinal length. 7. The modular rotor blade according to claim 1, further comprising at least one intermediate module, the intermediate module being adapted to be rigidly fixed to one of the first and second modules by a connection arrangement, the connection arrangement comprising a second connector rod bonded to at least one second receptacle adapted to receive the connector rod, and wherein the second connector rod and the at least one second receptacle have rectangular cross sections. 8. The modular rotor blade according to claim 1, wherein the connector rod and the receptacle are male and female box beams adapted to fit into each other. 9. The modular rotor blade according to claim 8, wherein the box beams comprise sealing flanges. 10. A modular rotor blade for a wind turbine, comprising at least a first module and a second module, wherein the first and second modules are adapted to be rigidly fixed to each other by a connection arrangement, the connection arrangement comprising a connector rod bonded to at least one receptacle adapted to receive the connector rod, the connector rod and the at least one receptacle forming a sealing flange, wherein the connector rod and the at least one receptacle have an elliptical cross section, and wherein a permanent bonding joint defined between the first and second modules comprises a substantially uniform bond line inducing a substantially uniform load distribution between the connector rod and the at least one receptacle. 11. A method for assembling a sectional wind turbine blade, said method comprising: providing a sectional wind turbine rotor blade having a first blade section and a second blade section; fitting together the first and second blade sections with a connector; forming a permanent joint between the first and second blade sections by: sealing the connector; and forming a permanent, substantially uniform bonding joint between a connector rod and at least one receptacle inducing a substantially uniform load distribution between the connector rod and the at least one receptacle, the connector rod and the at least one receptacle forming a sealing flange. 12. The method according to claim 11, wherein the permanent joint is formed with a uniform bond line.
