A fastening device applied to fasten a pair of handle supports on a skiing machine has an upper semi-circular clipping element which is complemented by a matching lower semi-circular clipping element to receive a bending terminal of handle support. A semi-circulr recess is provided at an external central region of the upper semi-circular clipping element, and a circular depression is provided at an external center region of the lower semi-circular clipping element. A cylindrical housing, mounted on a base of the skiing machine encases the upper and lower semi-circular clipping elements, and has two openings. A securing knob is applied to secure the upper semi-circular clipping element and the cylindrical housing together tightly, which is threaded through an opening on the cylindrical housing into the recess with a pad. A retarding bolt is disposed between the base, cylindrical housing and lower semi-circular clipping element. A spring element urges the retarding bolt to insert tightly therebetween.
