Abstract

A retaining clip configured to secure an elongate member to a generally planar panel is described herein. The retaining clip includes a first side wall, a second side wall opposite the first side wall, and an end wall interconnecting the side walls. The side walls define a gap configured to receive the panel. The retaining clip includes further includes a resilient first cantilevered prong projecting into the gap from the first side wall and a resilient second cantilevered prong projecting from into the first gap from the second side wall. Free ends of the first and second prongs are characterized as having a pair of pointed barbs on distal edges of the first and second prongs. The pointed barbs are configured to increase a removal force required to remove the panel from the first gap. A method of forming such a retaining clip is also described.

First claim

We claim:

1. A retaining clip configured to secure an elongate member to a generally planar panel, said retaining clip comprising:
a first side wall;
a second side wall arranged opposite the first side wall;
a first end wall interconnecting the first and second side walls, wherein the first and second side walls define a first gap therebetween that is configured to receive the panel though a first opening opposite the first end wall;
a resilient first cantilevered prong projecting into the first gap from the first side wall; and
a resilient second cantilevered prong projecting into the first gap from the second side wall, wherein free ends of the first and second cantilevered prongs define a sharp pointed barb on each distal edge of the first and second cantilevered prongs, wherein the free ends of the first and second cantilevered prongs form a concave arcuate shape having a constant radius between the pointed barbs, and wherein the pointed barbs are configured to increase a removal force required to remove the panel from the first gap.

2. The retaining clip in accordance with claim 1 , wherein the first and second cantilevered prongs form arcuate shapes relative to the first and second side walls respectively.

3. The retaining clip in accordance with claim 1 , wherein the first and second cantilevered prongs project angularly from the first and second side walls respectively.

4. The retaining clip in accordance with claim 1 , wherein the retaining clip further comprises:
a resilient third cantilevered prong adjacent the first cantilevered prong and projecting into the first gap from the first side wall; and
a resilient fourth cantilevered prong adjacent the second cantilevered prong and projecting from into the first gap from the second side wall, wherein free ends of the third and fourth cantilevered prongs define a sharp pointed barb on each distal edge of the third and fourth cantilevered prongs, wherein the free ends of the third and fourth cantilevered prongs form a concave arcuate shape having a constant radius between the pointed barbs, and wherein the pointed barbs are configured to increase a removal force required to remove the panel from the first gap.

5. The retaining clip in accordance with claim 4 , wherein the third and fourth prongs form arcuate shapes relative to the first and second side walls respectively.

6. The retaining clip in accordance with claim 1 , wherein the removal force required to remove the panel from the first gap is at least two times greater than an installation force required to insert the panel within the first gap.

7. The retaining clip in accordance with claim 1 , wherein distal edges of the retaining clip are rounded to minimize chafing of the elongate member.

8. The retaining clip in accordance with claim 1 , wherein distal edges of the each of the first, second, third, and fourth prongs define an angle of about 15 degrees relative to each other.

9. The retaining clip in accordance with claim 1 , wherein the retaining clip further comprises:
a third side wall arranged opposite the second side wall; and
a second end wall interconnecting the second and third side walls, wherein the second and third side walls define a second gap therebetween that is configured to receive the elongate member though a second opening opposite the second end wall.
