Abstract

A coupling member, for coupling profile bars having longitudinal grooves covered by profile walls so that a first profile bar is butt-jointed to a side wall of a second profile bar. The coupling member is inserted into the grooves aligned in one plane. The coupling includes an elongated counter holder insertable into the longitudinal groove of the first profile bar, and a tension tie incorporating a shaped head that is insertable into the longitudinal groove of the second profile bar and engages the profile walls from behind, and a shaft connected to the counter holder. The counter holder is rotatable on the tension tie by a pivot that engages the profile walls and is provided on one side with a tooth system that penetrates the groove bottom when the coupling member is tightened by rotating the counter holder.
