ABSTRACT:
A connecting element is provided for connecting together adjacent shuttering panels of the kind in which reinforcement strips with rows of holes provided therein are arranged at the edges of the shuttering panels and are dipsosed perpendicular thereto. The connecting element consists essentially of a curved lever arm (13) which tapers from a spigot part (17) to an end surface (18). The spigot part (17) adjoins a handle portion of the connecting element at a flange (16') defining an abutment edge (16). The handle portion is curved in essentially U-shaped manner and has a support surface (20) at the inside of its limb connected to the spigot portion (17). In operation the engagement end (18) of the lever arm is first introduced through two aligned holes in the adjacent reinforcement strips of two adjacent shuttering panels and the connecting element is then rotated about the abutment edge (16) so as to cause the spigot part (17) to enter into the two aligned bores. During this the lever arm clamps the two reinforcement strips together. In the engaged position shown in FIG. 2 the support surface (20) contacts one side of one of the connecting strips and the engagement surface (18) contacts the opposite side of the other reinforcement strip. The U-shaped handle of the connecting element has been pivoted downwardly so that the abutment end (12') thereof engages against the same side of the reinforcement strip (15') as the engagement surface (18). In this position the connecting element is reliably locked in place and the shuttering panels are reliably connected together.
