A holder made of plastic for vibration-insulating attachment of an oblong object such as a pipe or the like to a vehicle includes a base part with a bolt-accommodating opening and retainer parts that have a U-shaped retaining section with a recess that has a hollow inner surface and an insertion opening at which a resilient retaining finger is provided, which is able to hold an oblong object in the recess. The retainer parts are connected to the base part by means of thin, flexible wall elements. The base part has a frame with openings and the apex regions of the retaining sections on the side opposite from the insertion opening can move into these openings.
