A wiper assembly (100) is provided, comprising a wiper arm (110), a wiper blade (120), and a coupling device (130) configured to enable connection of the wiper blade (120) to the wiper arm (110), wherein the coupling device (130) comprises a first part (140) being connected to one of said wiper arm (110) or said wiper blade (120), and a second part (150) being connected to the other one of said wiper arm (110) or said wiper blade (120). The first part (140) comprises an engaging section (142) being configured to provide an axial fixation of the first part (140) relative the second part (150), and at least one recess (144) configured to provide a rotational fixation of the first part (140) relative the second part (150), and wherein the second part (150) comprises a receiving section (152) configured to receive the engaging section (142) of the first part (140), a locking device (160) arranged radially outwards of said first part (140) and comprising at least one radial protrusion (162) configured to fit with said recess (144) of the first part (140), and a wall (170) surrounding said locking device (160), wherein said wall (170) comprises a constricted section (172) whereby an inner wall (174) of said constricted section (172) is configured to press the radial protrusion (162) radially inwards when the constricted section (172) is axially aligned with the radial protrusion (162).
A wiper assembly, comprising a wiper arm, a wiper blade, and a coupling device configured to enable connection of the wiper blade to the wiper arm, wherein the coupling device comprises a first part being connected to one of said wiper arm or said wiper blade, and a second part being connected to the other one of said wiper arm or said wiper blade, wherein the first part comprises an engaging section being configured to provide an axial fixation of the first part relative the second part, and at least one recess configured to provide a rotational fixation of the first part relative the second part, and wherein the second part comprises a receiving section configured to receive the engaging section of the first part, a locking device arranged radially outwards of said first part and comprising at least one radial protrusion configured to fit with said recess of the first part, and a wall surrounding said locking device, wherein said wall comprises a constricted section whereby an inner wall of said constricted section is configured to press the radial protrusion radially inwards when the constricted section is axially aligned with the radial protrusion.
A coupling device configured to connect a wiper arm with wiper blade, the coupling device comprises a first part being connectable with one of said wiper arm or said wiper blade, and a second part being connectable with the other one of said wiper arm or said wiper blade, wherein the first part comprises an engaging section being configured to provide an axial fixation of the first part relative the second part, and at least one recess configured to provide a rotational fixation of the first part relative the second part, and wherein the second part comprises a receiving section configured to receive the engaging section of the first part, a locking device arranged radially outwards of said first part and comprising at least one radial protrusion configured to fit with said recess of the first part, and a wall surrounding said locking device, wherein said wall comprises a constricted section whereby an inner wall of said constricted section is configured to press the radial protrusion radially inwards when the constricted section is axially aligned with the radial protrusion.
