A clamping device for panel elements (3) portable along a top and bottom guide rail (1, 2), the elements being fitted with a guide (4, 5) mounted on the top and bottom edge of an element, the guide rails (1, 2) being provided with a pivoting point for the element (3), at which the element (3) is pivotable relative to a pivot spindle (6) constituted by a guide (4) on the top edge of the element and a guide (5) on the bottom edge of the element, at least one of the guides (4, 5), which constitute the pivot spindle (6), being adapted to set in a clamped position in the guide rail (1, 2) as the element (3) is pivoted relative to said pivot spindle (6). The guide (4) is adapted to clamp in place includes a locking member (7) with a circular-segment shapped cross section, adapted to be non-rotatable relative to the element (3) and having a straight portion (8) which is aligned essentially in parallel with the guide rails (1, 2) as the element (3) travels along the guide rails. For the locking member(7), the element pivoting point is fitted with a guide (9), having one (11) of its parallel flanks (10, 11) facing each other provided with a circular-arc shaped recess (12). The circular-segment shaped locking member (7) has a smallest diametral dimension (d) which is less than a distance (a) between the straight flanks (10, 11) of the guide and a largest diametral dimension (D) which is substantially equal to a maximum distance (A) between the opposite flanks of the guide (9) at the circular-arc shaped recess (12).
