ABSTRACT:
A clamp 100A for connecting formwork panels 50, 50 together at a right angle has a symmetrical shape and comprises a generally triangular central section 1, one intermediate lever 3 connected pivotally to each of opposed sides of the central section 1, and an L-shaped holding arm 2 connected to the intermediate lever 3 by means of a link 4 that is pivotally joined with both the intermediate lever 3 and the holding arm 2. The central section 1 has two equal sides a, a which extend perpendicular to each other and at which the central section 1 engages with joint members 52, 52 of formwork panels 50, 50. Notches 1c are formed on each side a, and are adapted to bite into one joint member 52. Each side a of the central section 1 is thus capable of engaging very closely with the joint member 52. The holding arm 2 is also provided with notches 2c, so that the holding arm 2 also can engage very closely with the joint member 52.
