[0025] Therefore, the wiper assembly and its connector according to the present invention enable the connector to have a complete appearance due to the fact that the engagement member is hidden inside a housing wall of the hollow connector, thereby enabling the connector to have a better appearance and preventing embrittlement of the engagement member due to exposure to sunlight for a long time and preventing breakage of the joining portion between the engagement member and the connector, thereby prolonging the service life of the connector and the wiper.

[0026] Advantageously, when the connector is connected to the wiper, a gap exists between the lower part of the connector and the body. Therefore, the user can remove the engagement element from this gap, which has the effect of facilitating the replacement of the wiper.

[0027] Advantageously, the joining groove is formed by at least two walls extending into the hollow interior of the connector, and the two second joining portions are located on two opposite walls. Consequently, the material for making the connector can be saved and the joining groove is given deformable elasticity, which has the effect of facilitating the replacement of the windshield wiper.

[0028] Advantageously, the two second joining portions are through holes penetrating through the two walls, and the two first joining portions are columns protruding from the surface of the joining base. Therefore, the two first joining portions and the two second joining portions have the effect of facilitating convenient joining and separation.

[0029] Advantageously, one of the housing walls forming the hollow connector comprises an inclined wall positioned on the engagement element. Consequently, the user can remove the engagement element from this inclined wall, which has the effect of facilitating the replacement of the windshield wiper.

[0030] Advantageously, the locating hole within the connector is configured to insert an open end of a rotating arm, and the engaging portion is engaged in a locating groove of the rotating arm. Therefore, the connector and the rotating arm have the effect of providing a solid joint.
