ABSTRACT:
A fastening strap configured as a loop is securable between a door and its associated frame to provide structure for attachment of exercise or physical therapy equipment to the door structure for support. The fastening strap is formed from a flexible elongate strip of webbing with an enlarged end portion which in a first species comprises a rolled portion of the first end portion of the webbing material and in a second species is a separate resiliently deformable element. The webbing strip extends from the enlarged end portion to form a loop and pass back over the enlarged end portion for fastening of the second end to the loop portion of the strip. The second end and adjacent the strips forming the loop are fastened to each other spacedly adjacent the enlarged end portion. A flexible coating is provided on a portion of the outer surface of one strip portion forming the loop to provide a higher frictional surface to contact a supporting door structure and to protect the strip from physical damage from the supporting door structure.
