Vibration-proof clamp

To provide a vibration-proof clamp with few component parts which can be assembled easily by hand the vibration-proof clamp (1) comprises a clamp body (10) having a holding part (10a) and a stud engaging part (20), the vibration-proof clamp (1) being made of a hard resin, and a rubber member (30) that covers the holding part of the clamp body. The holding part has a curved wall (17) for holding the elongated element from below and at least one elastic holding member (15) that extends slanting downward towards a holding space. The rubber member has a rubber curved part (37) that covers the curved wall of the clamp body and rubber holding member (35) that covers the elastic holding member. When the elongated member is attached, the elastic holding member can bend inside the holding member space (15s). The rubber element has a rubber curved extension part (37a) that curves upward along the outside of the elongated element continuing to the rubber curved part. The rubber curved elongated element is connected with the rubber holding element. The elongated element is not in direct contact with clamp body.
