Antivibration clamp for elongated objects

An antivibration clamp comprises a base made of hard resin and an object-holding portion of hard resin supported by the base. The object-holding portion includes a curved wall defining a recess for receiving an elongated object, and a resilient holding finger extending obliquely from the top of the curved wall or its vicinity toward the recess of the curved wall to press against the outer surface of an object received in the curved wall. The curved wall has an inner wall surface on which a plurality of elongated rigid ribs are formed to protrude inward and extend in the width direction of the curved wall with the ribs being spaced apart from each other in the circumferential direction of the curved wall. The inner wall surface and the ribs of the curved wall are coated with an antivibration material made of soft resin.
