A clamp of a thermally weldable material for a pipe of a thermally weldable material has two segments surrounding the pipe in a position of use of the clamp. The segments have heating mats of heatable electrical conduits integrated into inner surfaces of the segments. Each segment has two border edges facing one another in the position of use and clamped to one another by fastening elements. A first border edge of each segment has at least one segment flap projecting past the first border edge, and the second border edge has at least one pocket recessed relative to the second border edge. Segment flaps and pockets are complementary to the segment flaps and pockets of the opposed segment in the position of use. The heating mats have projecting flaps integrated into the area of the segment flaps and gaps in the area of the pockets. The segment flaps have a uniform thickness over their entire length and portions thereof have such a minimal thickness relative to the flap of the heating mat that, upon heating, the weldable material softens and melds in the inner contact zone between the circumferential surface of the pipe and the inner surface of the segment flap as well as in the outer contact zone between the outer surface of the segment flap and the inner surface of the pocket of the neighboring segment. After cooling a welding connection on both sides of the segment flap results. |
