<p>A stud clip fitting structure and a separable shell that is connected through the stud clip fitting structure. The stud clip fitting structure comprises a first member (10) and a second member (20). A clip hook part (11) and a bump part (12) are arranged on the first member (10). The second member (20) comprises a stud clip part (21) and a bone-position part (22). A distance between the stud clip part (21) and the bone-position part (22) is shorter than a distance between the clip hook part (11) and the bump part (12). The clip hook part (11) is adapted to the stud clip part (21). When the first member (10) moves relatively to the second member (20) to enable the clip hook part (11) to be separated from the stud clip part (21), the bone-position part (22) moves from one side of the bump part (12) to the other side and contacts the bump part (12).Buckling is implemented through cooperation between the clip hook part and the stud clip part, making installation convenient. When the clip hook part is separated from the stud clip part, the bone-position part contacts the bump part to form a suspended return structure, which facilitates final separation of the first member and the second member.</p>
