The invention comprehends a particular construction,
by various and numerous methods and means which
have been time consuming and costly. Further, in use,
the ends of the strips of material too frequently become
loosened or ruptured and therefor fail in their supporting
function.
In contradistinction, I have devised a novel means
whereby these di?‘iculties and objections are overcome. I
accomplish this by the provision of a device which ob
viates the need for special equipment and eliminates the
aforesaid objectionable inconveniences.
The principal objects of this invention are directed to

of strip material to the tubular frame members of furni~

to the webbing and consequently, the fastener will hold

When the fasteners, nested in the ends of the webbing,
