This invention relates to a fastener, for retaining two partsin association with each other, one of the parts extending through or around the other part.

In greater detail, the fastener comprehends a simplified fastening device which may take the form of a single piece of material such as steel of a resilient quality which is bent to a formation in which it may be employed for retaining a window frame in association with an opening in a wall, such as a window frame of the class employed in the front of a cabinet for a television and/ or a radio receiving set.

Of various media which have been employed for attaching windows, including their frames, to the casing of cabinets at openings therein through which a television picture or a dial is viewed, none has been without defects for assembly line manufacture, especially when the window, is of a plastic material and is an integral part of the frame. For example, fasteners of one class are too expensive insofar as their first cost is concerned. Otherfasteners cannot-be assembled quickly enough. And still others are unsuitable for use with comparatively soft plastic material of the window frames and their use is frequently followed by fracture or deformation of the plastic parts.

Because of the present invention, a fastener may now be provided which obviates the foregoing disadvantages since the fastener is inexpensive of manufacture, may be produced from inexpensive material and which calls for no special skill in its application.

Other advantages of the invention, aswell as the invention itself, will become apparent from the following description of embodiments thereof, which description is illustrated by the accompanying drawings and forms a part of this specification.

In the drawings:

Fig. 1 is a fragmentary sectional view taken on line l-[ of Fig. 4, the fastener being in complete- I 1y assembled relationship to the other parts;

Fig. 2 is a sectional view, corresponding to Fig. 1, showing the fastener in the process of being assembled with the frame;

Fig. 3 is a perspective view of the fastener;

Fig. 4 is a fragmentary elevational View from the right hand side of the parts shown in Fig. 1;

Fig. 5 is a sectional view taken on line 5-5 of Fig. 4;

Fig. 6 is a perspective view of a second embodiment of the fastener; and

Fig. 7 is a perspective View of a third embodi- .ment of the invention.

its edge portions only, to provide a window portion 12 centrally of the frame, through which an object such as a television picture tube or dial of a radio receiving setwithin the cabinet may be viewed. A flange portion l3, which extends over the external surface of the cabinet from opening {3, limits di spla cenient of the frame tothe right (Fig. l), and displacement thereof transversely of the axis of said opening is precluded by intimacy of association of a rim portion M with that portion of the cabinet defining the opening 9. The rim l4 extends to an edge thereof l6, adjacent the rear extremity of opening 9, and

is formed with lugs I1, any number of which may parallel arms 23.

be present on the edge and which are preferably integral with the window frame i l. Each of the lugs I1 is apertured by a slot [8 to provide a seat or pocket for a purpose later to be described. These seats may also be provided by recesses molded or cut in the lugs, or may be provided by means of other members, having seats thereon, molded in the lugs.

A novel clip or fastener I9 is adapted to cooperate with each of the seats for anchorage of the clipto the frame II, and concurrently, for Securing theframe to the cabinet. For a clearer understandingv of the operation of this device, reference should be made to Fig. '3 wherein the fastener is shown as a single piece of substantially resilientwire bent to the conformation shown.

As will be noted, the fastenerincludes at least one hook or intermediate portion 2! which is between and offset from the ends of a pair of inner parallel arms 22 bent at the ends to continue laterally away from each other to outer Each of the pair of arms 22 provide, with arms 23, a wing portion 24 adapted to engage the inner surface of the rim 5% while the hook portion 2! extends into the slots-l8. Desirably, of course, the arms 22 are only slightly closer to each other than the length of the slot l8, so that when in association with frame II,
