Abstract
A clamp for a cylindrical includes a base portion and a clamping portion which define together a common through opening for passage of a cylindrical element. Fasteners are provided to brace the base portion and the clamping portion to thereby hold the cylindrical element in a clamping zone. The base portion and the clamping portion are each provided with an attachment surface, wherein the attachment surface of the clamping portion includes a cutout formed with internal teeth for optional positive engagement of external circumferential teeth of a protrusion of a base portion of a further such base portion or external circumferential teeth of a protrusion of a connection piece, such that the internal and external teeth are constrained against rotation. Thus, a series of clamps can be stacked on top of one another.
