An ornament cap for covering a groove formed in a first casing which is fastened to a second casing by means of a fastening device accommodated in the groove, the cap includes a seat formed in the groove and an insert for engaging with the seat. At the engaging interface of the insert and the seat, a vertical limiting means is provided to form a vertical limiting position for preventing the insert from vertically separating from the groove after engagement, and a horizontal limiting means is provided to form a horizontal limiting position for preventing the insert from separating from the groove horizontally along the groove. There are a first stable state defining a separated state between the insert and the seat and a second stable state for engaged state between the insert and the seat. The horizontal limiting means may jump from the first stable state to the second stable state under an external force is applied to the horizontal limiting means to complete the engagement of the insert and the seat. Under another external force and a transverse force, the horizontal limiting means may jump from the second stable state to the first stable state for separating the vertical limiting means to disengage the insert from the seat.
