Abstract
Abstract A bracket for fixing to a prescribed member a flexible tube, such as the protective boot installed in an automobile suspension device, includes a stationary ring fixed on the prescribed member. A spacer ring is fitted to the stationary ring and provided with resilient supporting arms, and a fastening ring is fitted to the spacer ring for fastening a terminal part of the flexible tube. Alternatively, the stationary ring fixed on the prescribed member is provided with the resilient supporting arms, and the fastening ring is fitted to the stationary ring for fastening the terminal part of the flexible tube. By the fact that the fastening ring is rotatably retained directly or through the spacer ring on the stationary ring by virtue of the resilient force derived from the resilient supporting arms, provided either on the spacer ring or on the stationary ring, the bracket is infallibly fixed to the prescribed member through the stationary ring, and the flexible tube fastened to the fastening ring is allowed to rotate freely relative to the stationary ring. Thus, it is possible to eliminate the possibility that the terminal part of the flexible tube will be twisted as a consequence of the rotation of the prescribed member and will be eventually broken through fatigue.
