A clamped connection for channel sections (1, 2), lying one inside the other, of a yielding mine support. The clamped connection completely encloses the channel sections (1, 2) and consists of an embracing clamp (3) and a clamping bolt (9) arranged on one side. So that this clamped connection can be produced economically in a simple manner, it being possible for the clamping forces to be applied in a simple manner, the clamp (3) is of U-shaped design, where one clamp leg (4) rests on the flanges (10) of the inner channel section (1), the clamp base (6) encloses the section webs (11) on one side of the channel sections (1, 2), and the second clamp leg (5) bears against the base (12) of the outer channel section (2) and extends freely to open the clamp (3), and the clamping bolt (9) on the other side of the channel sections (1, 2) engages in the front ends (7, 8) of the clamp legs (4, 5). <IMAGE>
