Abstract: A snap-fit connector includes a female component and a male component. The female component has a retaining hole and two through bores communicating spatially with the retaining hole. The male component has two spaced-apart hooks inserted into the retaining hole. Each of the hooks has a resilient arm, and a protrusion retained in a respective one of the through bores. The protrusion of each of the hooks has an abutment surface abutting against the female component, and a positioning recess formed in a guide surface thereof and accessible via the respective one of the through bores.

Abstract: A joint assembly includes a stud, an inner casing and an outer casing. The stud includes a rod segment and a ball segment. The rod segment extends along a first axis and has opposite first and second ends. The ball segment is connected co-movably to the first end of the rod segment. The inner casing is mounted around the stud and rotatable relative to the stud about the first axis, and has a second axis perpendicular to the first axis. The outer casing is mounted around the inner casing and rotatable relative to the inner casing about the second axis. The second end of the rod segment of the stud extends out from the outer casing.
