An improved clamp (1) for locking pipes and/or cylindrical bodies in general, including at least one first jaw (10) that is associatable with a supporting structure, a second jaw (20), and an articulation means (30) interposed between the first jaw and the second jaw in order to allow the relative rotation of the two jaws about a tilting axis (100), between an open configuration and a closed configuration in which the two jaws form a substantially circular locking seat. The particularity of the present invention resides in that the clamp includes an elastic means (50) that is functionally connected to the two jaws and is adapted to facilitate their opening and/or closure.
