Abstract
Bundling of objects using a harnessing device with a locking head and a strap with teeth that are controlled by stretching. The locking head contains a pawl or tang that engages the teeth of the strap by wedging. A wedging tooth is desirably on the locking tang as well, and a further tooth to promote locking is desirably included in the locking head. The strap is advantageously molded of stretch reorientable material which is subsequently stretched to control the profile of the teeth which are engaged by the locking tang and head.
