BACKGROUND OF THE INVENTION:
[002] Traditionally, in a vehicle such as a scooter there is provided a handle cover assembly disposed so as to cover a handlebar. The handle cover assembly generally comprises a first cover part and a second cover part that are coupled together. In the traditional handle cover assembly, certain amount of gap is left between the first cover part and the second cover part in an assembled state. Since, the gap between the first cover part and the second cover part is visible, an aesthetics of the vehicle is adversely affected. Thus, attempts are made to reduce the amount of gap (as the gap cannot be eliminated). Traditionally, the gap between the first cover part and the second cover part is minimized/controlled only by using screws or hard fasteners. However, using the screws and hard fasteners have a variety of disadvantages, including but not limited to an increase in the number of parts, increase in a weight of the handle cover assembly, increase in a time needed to assemble the handle cover assembly. Also, the screws and hard fasteners are visible which affects the aesthetic of overall vehicle. Thus, there exists a need to address the aforesaid disadvantages.
