The invention relates to a coupling element ( 30 ) for coupling a windshield wiper blade unit ( 14 ), which coupling element defines an upwardly open hollow housing ( 36 ) into which a connector ( 16 ) is disassemblably received, and comprises two vertical longitudinal side flanges ( 32 ) that are interconnected via a transverse rod ( 34 ) forming a transverse hinge axis (A), a horizontal bottom wall ( 50 ), and two vertical transverse webs, namely a front transverse web ( 46 ) and a rear transverse web ( 48 ), which webs interconnect respectively the associated front ends and the associated rear ends of the side flanges ( 32 ); the side flanges ( 32 ), the transverse webs ( 46, 48 ), and the bottom wall ( 50 ) defining said upwardly open hollow housing ( 36 ) of the coupling element ( 30 ); said coupling element being characterized in that it is provided with at least one channel ( 54, 56 ) putting the bottom of the hollow housing ( 36 ) into communication with the outside, enabling any liquid present on the top surface ( 50 s) of the bottom wall ( 50 ) to be removed. The invention also relates to a windshield wiper blade unit ( 14 ) and to a windshield wiper ( 10 ) including such a coupling element ( 30 ).
