A fastener for securing pipes to a rack includes a tensioning mechanism, a bracket for mounting the tensioning mechanism to the rack, and a flexible cord. The tensioning mechanism has a tubular housing, a threaded shaft mounted in the housing to rotate about its longitudinal axis while being fixed axially, and a movable bracket threaded on the threaded shaft and mounted in the housing so that it will move up and down along the length of the housing in response to rotation of the threaded shaft. The flexible cord has one end fixed to the mounting bracket and knots spaced along a portion of the length of the cord adjacent its free end. The cord is wrapped around the articles to be held on the rack and one of the knots in the cord is selectively and releasably positioned in a notch in the movable bracket. Rotation of the threaded shaft in one direction will cause the cord to tighten about the articles and rack to fixedly secure the articles to the rack.
