Abstract: A clamp for securing a pipe to a supporting structure and including a base having a foot for attachment to a supporting structure and a head having a seating for accommodating a pipe and two walls for defining the seating, an entrance for the pipe extending between the two walls, and an U-formed strap for clamping a pipe placed in the seating to the base. The strap has two legs for engaging opposite contact faces formed in the base and a curved bottom for surrounding the pipe together with the walls of the head. The radius of curvature of the inner side of curved bottom of the U-formed strap is larger than that of the seating. The clamp enables a secured pipe to noiselessly expand or contract depending upon the temperature and is mainly corrosion free due to the clearance that is formed between the strap and the clamped pipe.
