Abstract: A clamp for fastening an elongated element to a carrier has a first receiving region for the carrier and a second receiving region for the elongated element. The clamp has a peripheral wall defining first and second end faces. The first receiving region is delimited by a first wall section of the peripheral wall, and the second receiving region is delimited by a second wall section of the peripheral wall. The first wall section and the second wall section are mutually contiguous at two connecting locations. The first and second receiving regions between the connecting locations are mutually connected and conjointly form a single receiving space. The peripheral wall in the closed state of the clamp extends in a fully encircling manner about the receiving space. One of the wall sections has two partial wall sections and the respective ends thereof form a closure for releasably connecting the partial wall sections.
