Disclosed is a fixture for external frame sections (1) of solar modules on a profiled support (2). Said fixture comprises a clamping piece support (3) which can be moved in a guided manner on the profiled support (2) in the longitudinal direction of the profiled support (2) and can be braced with the profiled support (2) so as to enclose a frame section (1) of the solar module and a clamping piece (4) that is guided within the clamping piece support (3). The clamping piece (4) is designed as a double-angled profiled element which has legs (4.1, 4.2) extending in opposite directions. The upper leg (4.1) embraces the frame section (1) of the solar module while the lower leg (4.2) is disposed in and on the clamping piece support (3) so as to be vertically adjustable in a guided manner in the moving direction (7).
