Abstract: A fastener for a pipe is able to prevent an end of a stud to which the fastener is attached from puncturing a fuel tank or breaking other parts of a car body and causing the fuel tank to rupture when a collision occurs. The fastener comprises a fastener main body and a protective member. The fastener main body has a base, pipe fastening portions connected to the base, and a stud engaging portion connected to at least one of the base and the pipe fastening portions to engage a stud extending from a support. The stud engaging portion has a stud receiving hole for receiving the stud. A protective member is attached to at least one of the stud engaging portion and the base to cover the end of a stud in the stud receiving hole and has sufficient rigidity to prevent the end of the stud from protruding out of the stud receiving hole.
