Abstract: Disclosed herein is an elastic cord tie-down of the bungee or shock cord type and in which means are provided by which to manually adjust the article-engaging loop of the tie-down to articles of diverse geometries and dimensions.

Abstract: An adjustable tension fastener which consists of a rigid loop-hook having a rigid loop member and a rigid hook member and a flexible cord connected to the rigid loop member by a pull-through knot for defining a tension portion and a reserve portion of the cord. A binder is used for selectively adjusting the length and tension of the tension portion and securing the rigid loop-hook to a portion of the flexible cord.

Abstract: A wire is bent into an enclosed loop and double bent at each end to form a quadruple element hook extending from the loop. At least one elasticized loop is attached to the loop-hook by a pull-through knot. Additional elasticized loops may be added and alternated with rigid closed loops as desired. The entirely closed loop system may be used linearly or in a spiderlike fashion to bind external objects. Alignment of the two sides of the elasticized loop with the two sides of the quadruple element hook provides efficient load transfer from hook to elasticized loop. Prebending of the loop-hook opposite the hook further insures alignment.
