Split collar

Claim 2

A collar for surrounding an article comprising: first and second collar sections having abutting edges, internal surfaces and external surfaces, the internal surfaces of said collar sections being adapted to surround said article when said abutting edges are adjacent one another and said internal surfaces defining an opening through said collar to accommodate said article; groove means formed in said external surfaces of said collar sections and lying in a plane which is perpendicular to said opening, said groove means comprising a pair of parallel and spaced apart grooves extending about said external surfaces, coupling means on one of said first or second collar sections; elastic means coupled to said coupling means and surrounding said first and second collar sections in said groove means and holding said collar sections together about said article.

Claim 3

The invention set forth in claim 1 wherein said coupling means comprise first and second coupling means lying adjacent to but spaced apart from one another and intermediate said grooves.

Claim 4

The invention set forth in claim 2 wherein said elastic means comprises a loop of elastic material having ends coupled respectively about said first and second coupling means and an intermediate portion lying in said grooves.

Claim 5

The invention set forth in claim 3 wherein said elastic loop comprises a rubber loop.

Claim 6

A split collar for surrounding a tubular article comprising: first and second collar sections each being generally C-shaped, each of said collar sections including an inner surface and an outer surface and said collar sections forming a generally cylindrical opening therethrough when said sections are adjacent one another, groove means formed in said outer surface of said sections and lying in a plane which is generally perpendicular to the axis of said cylindrical opening said groove means comprising a pair of parallel and spaced apart grooves extending about said outer surface, coupling means on one of said collar sections, elastic means coupled to said coupling means and surrounding said first and second collar sections in said groove means and holding said collar sections together about said article.

Claim 7

A split collar for surrounding a tubular article comprising: first and second collar sections each being generally C-shaped, each of said collar sections including an inner surface and an outer surface and said collar sections forming a generally cylindrical opening therethrough when said sections are adjacent one another, groove means formed in said outer surface of said sections and lying in a plane which is generally perpendicular to the axis of said cylindrical opening said groove means comprising a pair of parallel and spaced apart grooves extending about said outer surface, coupling means on one of said collar sections, elastic means coupled to said coupling means and surrounding said first and second collar sections in said groove means and holding said collar sections together about said article.

Claim 8

The invention set forth in claim 5 wherein said coupling means comprise first and second coupling means lying adjacent to but spaced apart from one another and intermediate said grooves.

Claim 9

The invention set forth in claim 6 wherein said first and second coupling means comprise portions of said outer surface intermediate said grooves and wherein said one collar section is indented intermediate said grooves and said indentation extends under said outer surface.

Claim 10

The invention set forth in claim 6 wherein said elastic means comprises a loop of elastic material having ends coupled respectively about said first and second coupling means and an intermediate portion lying in said grooves.

Claim 11

The invention set forth in claim 8 wherein said elastic loop comprises a rubber loop.

Claim 12

The invention set forth in claim 5 wherein the diameter of said opening varies along the length of said collar.

Claim 13

A collar for covering the junction of two co-axial tubes, one of which is slidably received in the other, said collar comprising: first and second collar halves, said collar halves each having first and second ends and a generally C-shaped wall extending therebetween, projections extending inwardly from said first and second ends, said projection extending from said first end forming a first annular surface adapted to surround one of said tubes and the projection extending from said second end forming second annular surface adapted to surround the other of said tubes; a pair of spaced-apart grooves formed in the outer surface of said wall, each of said grooves lying in a plane which is perpendicular to the axis of said annular surfaces, a dividing ridge being formed intermediate said grooves, a cut-out portion in said ring in one of said collar halves said cut-out portion extending into said wall and back under said ridge to form a pair of facing projections intermediate said grooves; and elastic loop means coupled to said projections and stretched about said first and second collar halves to hold said collar halves together.

Claim 14

A collar for covering the junction of two co-axial tubes, one of which is slidably received in the other, said collar comprising: first and second collar halves, said collar halves each having first and second ends and a generally C-shaped wall extending therebetween, projections extending inwardly from said first and second ends, said projection extending from said first end forming a first annular surface adapted to surround one of said tubes and the projection extending from said second end forming second annular surface adapted to surround the other of said tubes; a pair of spaced-apart grooves formed in the outer surface of said wall, each of said grooves lying in a plane which is perpendicular to the axis of said annular surfaces, a dividing ridge being formed intermediate said grooves, a cut-out portion in said ring in one of said collar halves said cut-out portion extending into said wall and back under said ridge to form a pair of facing projections intermediate said grooves; and elastic loop means coupled to said projections and stretched about said first and second collar halves to hold said collar halves together.

Claim 15

The invention set forth in claim 11 wherein the diameter of said first annular surface is less than the diameter of said second annular surface.
