A fabric sign having a pair of parallel support elements (1, 2) and a fabric (3) with two parallel edge portions (4, 5) for assembly on one each of the support elements, at least one of the support elements comprising a frame profile (7) with a counter support (12) having an inner wall section (17) forming a continuation of said attachment part (14), an outer, flange−like wall section (19) with a free supporting end (20) to form a pivot (A), and an end wall section (18) connecting the inner and outer wall sections with each other, said wall sections defining between them a clamping pocket (25), and a clamping profile (8) for clamping the fabric to the frame profile, which clamping profile has a pressure part (28) for manual actuation, retaining devices (48, 49) for retaining the edge portion of the fabric, and an engagement part (27) arranged to cooperate with the inner and outer wall sections of the counter support when the pressure part is pressed against the attachment part while the clamping profile is turned about said pivot, at the same time creating tensile stress in the fabric. In accordance with the invention the outer wall section of the counter support has an extension that allows the clamping profile to exceed an equilibrium, at which exceeding of the equilibrium the tensile stress acts to move the clamping profile to a locked position in which the clamping profile is in locked engagement with the frame profile, said locked position being maintained by the tensile stress.
