Attachment for sectional heating elements

The invented attachment for sectional heating elements consists of a clamping part (2) and an attachment part (16) between which there are fastened two sections (1) of the heating element. In the clamping part (2) there is fastened a metallic screw part (3). On each side of the clamping part (2) there are performed bearing surfaces (4) of concave form and symmetric to the clamping part (2) central axis. The bearing surfaces (4) encompass partially the respective section (1) and are flush with outer surface thereof. Distance (X) of the bearing surfaces (4) at places lying nearest to the clamping part (2) central axis is greater than the distance of two adjacent sections (1) at places that lie nearest to the clamping part (2)) central axis, too. Each bearing surface (4) is followed up with a vaulted wall (6). Between the vaulted walls (6) there is performed on the clamping part (2) side turned toward the attachment part (16) a recess (5) of concave form. In the recess (5) there is made a slot (9) for mounting tools. In the metal-made attachment part (16) there are performed through-holes (17) and a screw (15) intended for screwing in the screw part (3) passes through the attachment part (16).
