Abstract
The invention relates to a wiper frame (10) comprising a device (24), in particular an aerodynamic deflector, for dis-pensing and/or spraying liquid, comprising at least one liquid flow channel (26), a longitudinal end (27) of which opens on an end face (28) of the device (24), a plug (40) for closing off the longitudinal end (27) of the liquid flow channel (26), which is inserted inside a longitudinal end section (27) of said channel (26), and a tip (30) arranged opposite the end face (28) of the device (24), characterised in that the closing plug (40) is a separate component from the tip (30), such as a spherical ball, such that the tip (30) and the plug (40) together ensure the closing off of the longitudinal end (27) of the liquid flow channel (26).
