## Abstract

The invention contemplates a unitary clip of ductile sheet metal in the form of a peripherally continuous elongate rectangular frame which is bent at its longitudinal midsection. The frame defines a window between its bent longitudinal legs, such that after inserting a loop-defining fold of cable, dropwire or the like through the window, the longitudinal ends of the frame may in a simple operation be crimped toward each other and into compressionally clamping engagement with adjacent regions of the folded cable, thereby also frictionally engaging to each other the adjacent regions of the folded cable.

## Claims

### Claim 1

As an article of manufacture, a support clip for a dropwire or the like, comprising a formed unitary blank of ductile metal sheet, the planiform of the blank being a peripherally continuous elongate rectangular frame surrounding a central open rectangular window region, said frame comprising two elongate parallel legs and two short end legs integrally connecting the longitudinal ends of said elongate legs, the length of said elongate legs along the length of said window region being at least twice the length of said short end legs along the width of said window region, like longitudinally central obtuse-angle bends in each of said elongate legs, whereby the span between end legs is less than the length of said elongate legs but is nevertheless greater than the length of said short end legs, the width of said window being sized for accommodation of the width of dropwire to be secured to a support and said span between end legs being greater than the combined double thickness of the dropwire, whereby a loop of the dropwire may be inserted through the window within said span with portions of the dropwire on both sides of the loop in adjacency to the combined extent of double the dropwise thickness, further whereby the clip may then be secured by crimping said end legs toward each other to reduce said span and in compressed squeezing engagement with said dropwire portions to permanently retain the loop, with said longitudinally central bends permanently reduced from said obtuse angle.

### Claim 2 (depends on 1)

The article of claim 1, in which said end legs are each at bent offset with respect to adjacent regions of said elongate legs.

### Claim 3 (depends on 2)

The article of claim 2, in which said bent offsets are such as to orient said end legs at an acute angle with respect to each other.

### Claim 4 (depends on 1)

The article of claim 1 in which said end legs are of longitudinal extent which is a multiple of the thickness of the metal blank, said bent offsets being each fully contained within the body material of the involved end leg.

### Claim 5 (depends on 1)

The article of claim 1, in which the longitudinal outer-end edge of each end leg is characterized by a recess profile.

### Claim 6 (depends on 5)

The article of claim 5, in which the recess profile is of lateral extent substantially coincident with the window width.
