[0056] The hose connector 104 has a through hole 120 for receiving the pivot shaft 2.
[0057] The outer perimeter 122 of the hose connector 104 may be fitted with a waterproof seal. This seal may be made of rubber.
[0058] The hose connector 104 has a fluid inlet port 124 on its rear face 118 and a fluid outlet port 126 on its front face 116. Figure 1 and Figure 2 In this configuration, the wash fluid hose 6 is connected to the fluid inlet port 124. Similarly, another wash fluid hose can be connected to the fluid outlet port 126, which is fixed to the windshield wiper to be attached to the pivot shaft 2.
[0059] A check valve can be installed in the fluid inlet port 124. The purpose of this check valve is to prevent the washing fluid from flowing back from the fluid outlet port 126 to the fluid inlet port 124.
[0060] In this embodiment, the hose connector 104 includes a plate-shaped body 128 and an integral fluid conduit 130 fastened to the body 128. In this case, both the fluid inlet port 124 and the fluid outlet port 126 are part of the fluid conduit 130.
