Abstract
Abstract A resilient wire attachment clip has two respective longitudinally extending; elongated, loop portions positioned in two mutually parallel planes, each of the loops formed by an internal limb and an external limb connected by a resilient arc portion that extends through a slot in a housing wall, the external limbs of the two loop portions normally lying within a pair of parallel grooves on the exterior of the housing wall with the ends of the external limbs connected by a transversely extending portion that is spaced outwardly from the housing wall, the internal limbs of the two loop portions have hook-shaped free ends which with slight prestress engage two abutments on the interior of the housing wall to support the clip between the two abutments and the interior surface of the housing wall at the point of an interiorly directed bend in the internal limbs, with the major portion of the diameter of the loop arc portions positioned interior of the housing wall.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
247 words
A resilient wire clip in combination with a body portion for attaching the body portion to clothing or the like, comprising a body portion having a pair of spaced apertures therethrough, a pair of U-shaped loop portions forming the sides of the resilient wire clip and positioned in spaced parallel planes at substantially right angles to the plane of said body portion; the U-shaped loop portions including inner leg portions positioned on the inner side of said body portion and outer leg portions positioned on the outer side of said body portion joined by bight portions which extend through the spaced apertures in said body portion; said body portion having a pair of parallel grooves in its outer surface in aligment with said pair of spaced apertures; said outer leg portions positioned in said grooves in the position of relaxation of the resilient wire clip; a central portion (6) joining the ends of the outer leg portions of the pair of U-shaped loop portions of the resilient wire clip and being spaced from the outer surface of said body portion; said inner leg portions having free ends terminating in hook-shaped portions, a pair of abutments on the inner side of said body portion, said hook-shaped portions engaged with said pair of abutments and said inner leg portions having a medial portion in contact with the inner side of said body portion to slightly prestress said resilient wire clip and position said outer leg portions in said grooves.
Claim 2
Dependent Claim
