A windshield wiper assembly adapted to be mounted to the attachment portion of a wiper arm that imparts reciprocal motion to the windshield wiper assembly across a surface to be wiped, said windshield wiper assembly comprising: a wiper blade adapted to contact the surface to be wiped; a coupler assembly operatively mounted to said wiper blade and serving to interconnect said wiper blade to the wiper arm; said coupler assembly including a coupler having a body including a pair of sidewalls, a channel defined between said sidewalls and extending substantially parallel thereto, said channel adapted to cooperatively receive the attachment portion of the wiper arm; and a latching mechanism operatively mounted to said body and moveable between an open position spaced from said channel and a closed position to secure the attachment portion of the wiper arm between said latching mechanism and said body thereby securing said coupler to the attachment portion of the wiper arm; said latching mechanism including a locking member, said locking member serving to secure said latching mechanism in said closed position; said locking member including at least one flexible arm, said body defining a retainer, said flexible arm adapted for releasable engagement with said retainer so that said latching mechanism is snap fit relative to said body when in said closed position, characterized in that said latching mechanism in its closed position is disposed over said channel and that said latching mechanism defines a top wall and a pair of sidewalls depending therefrom, said flexible arm having a first portion extending cantilevered from said top wall in a first direction, a second portion spaced from said first portion extending in a direction opposite said first portion and terminating in a distal end, a shoulder formed on said second portion spaced from said distal end, a hinge portion interconnecting said first and second portions (108, 110) such that said second portion flexes upon coming into contact with said retainer to move toward said first portion until said shoulder engages said retainer and locks said latching mechanism in said closed position. a wiper blade adapted to contact the surface to be wiped; a coupler assembly operatively mounted to said wiper blade and serving to interconnect said wiper blade to the wiper arm; said coupler assembly including a coupler having a body including a pair of sidewalls, a channel defined between said sidewalls and extending substantially parallel thereto, said channel adapted to cooperatively receive the attachment portion of the wiper arm; and a latching mechanism operatively mounted to said body and moveable between an open position spaced from said channel and a closed position to secure the attachment portion of the wiper arm between said latching mechanism and said body thereby securing said coupler to the attachment portion of the wiper arm; said latching mechanism including a locking member, said locking member serving to secure said latching mechanism in said closed position; said locking member including at least one flexible arm, said body defining a retainer, said flexible arm adapted for releasable engagement with said retainer so that said latching mechanism is snap fit relative to said body when in said closed position,
