Abstract: A pipe fastener which is capable of holding pipes without requiring a cover, attaching the pipes easily and enhancing a high mounting force of pipes while retaining the vibration absorbing function. The fastener 14 comprises a pipe holder 15 to hold pipes 2 and a panel fixing portion 17 to be fixed to a panel 5. The pipe holder 15 comprises a pipe engagement portion 18 which receives the pipes inside thereof and engages with them, a damper portion 19 of a vibration absorbing material disposed on the outer portion of the pipe engagement portion, and a holder portion 21 connected to the panel fixing portion to hold the outer portion of the damper portion. The pipe engagement portion 18, the damper portion 19 and the holder portion 21 are connected with each other as one piece.

Abstract: A bolt fastener (1) is attachable to a bolt (23) by pressing the base (3) onto the bolt to receive the bolt in a receiving hole (2) of the base (3), while the fastener (1) has an increased pulling resistance force (pulling load) against a pulling force of the fastener from the bolt. An inner wall (9) of the bolt receiving hole (2) is provided with a pair of opposed engagement means (10) member into engagement with a threaded portion of the bolt as the received in the bolt receiving hole (2). Each of the engagement means (10) comprises a plurality of resilient arms (15,17) extending from the inner wall (9) of the bolt receiving hole (21) toward the center of the hole and a plate-like engagement portion (18) supported by the resilient arms to extend longitudinally with respect to the bolt receiving hole.
