An apparatus for securing articles to structural members includes a main strap assembly having at least three distinct portions configured for forming a secure loop by attachment of at least one of the portions to another of the portions. The apparatus further includes a pair of parallel ancillary strap assemblies attached transversely to the main strap assembly. Each of the pair is attached to a respective one of ancillary releasable engagement mechanisms at an end thereof, for forming an engageable loop. The ancillary strap assemblies can be used to attach the main strap assembly parallel to an elongate structural member. The secure loop of the main strap assembly can be used for securing a heavy article to a bicycle frame, or the like.
