ABSTRACT:
A fastener for bundling wires or packaging other articles in which the ends of a smooth flexible plastic strap are inserted into parallel passageways through a plastic body and retained by locking ears extending into the passageways. An anchor member, formed from a single piece of spring sheet metal, includes a base portion, the two oppositely-extending locking ears and two intermediate oppositely-extending retaining ears that retain the anchor member within the body. The locking ears extend into the passageways to cinch the strap and prevent its being withdrawn. The outer ends of the locking ears are beveled to improve the holding power of the head. When the fastener has been applied to tie a bundle of articles, the forces operating on the fastener are in directions transverse to the axes of the passageways, thereby substantially increasing the holding power of the fastener. In another embodiment, only one passageway extends completely through the body, the other passageway being closed at one end and permanently retaining therein one end of a pre-cut plastic strap. The anchor member fastener is formed from a continuous sheet metal strip by a progressive die that forms and inserts the anchor member into the head where it is retained by the outward flexing of the retaining ears. Means are provided for releasing and re-using the fastener.
