Abstract: There is provided a clamp for clamping an object from an outer side of the object to fix the object while the object has a cross-section with a circular outer periphery. The clamp includes: a hard segment that is made of a hard material and is shaped in a tubular form; and a soft segment that is made of a soft material and is located on an inner side of the hard segment. The soft segment includes: an arcuate portion which has an inner edge that is arcuate; and a plurality of projections which project inwardly from the arcuate portion and is configured to urge the object. Each of the plurality of projections has a relief hole that extends through the projection such that the relief hole has a shape that corresponds to an outer shape of the projection.
