Abstract

A pipe clamp includes a wall part (1) with at least one bracket (3) located on its outside surface. At least one attachment part (2) is engageable in the bracket (3) and projects laterally outwardly from the wall part.

Claims

1. Pipe clamp with an annular wall part (1, 21) having a central axis and a circumferentially extending outside surface, at least one attachment part (2) extending radially outwardly from said outside surface of said wall part (1, 21), wherein the improvement comprising that said attachment part (2) having a radially inner section detachably connected to the outside surface of said wall part (1, 21) and a radially outer section, said wall part (1, 21) comprises at least one bracket (3, 22, 23) projecting radially outwardly from the outside surface thereof, and said attachment part being detachably connected to said bracket, and wherein said bracket forms an opening extending parallel to said central axis and arranged to receive said radially inner section of said attachment part.

2. Pipe clamp, as set forth in claim 1, wherein a plurality of said brackets (3, 22, 23) are disposed in at least one circumferentially extending row on the outside surface of said wall part (1, 21).

3. Pipe clamp, as set forth in claim 2, wherein said brackets (3, 22, 23) are located at equal spacings from one another in the circumferential direction of said wall part (1, 21).

4. Pipe clamp, as set forth in claim 1, wherein said attachment part (2) comprises an elongated section having a hook (4) at one end insertable into said bracket (3, 22, 23) with said hook (4), extending in the axial direction of said wall part (1).

5. Pipe clamp, as set forth in claim 4, wherein said wall part has a radially inwardly directed end side at each of opposite circumferentially extending sides of said wall part extending transversely of the central axis, and said hook (4) having an opening facing towards one of the end sides of said wall part (1, 21).

6. Pipe clamp, as set forth in claim 4, wherein said hook (4) is formed as a spring clip for frictionally engaging said bracket (3, 22, 23).

7. Pipe clamp, as set forth in claim 5, wherein said hook (4) is formed as a spring clip for frictionally engaging said bracket (3, 22, 23).

8. Pipe clamp, as set forth in claim 4, wherein said hook (4) comprises a snap-in element (5) for engagement in an opening extending through a wall in said bracket (3, 22, 23).

9. Pipe clamp, as set forth in claim 5, wherein said hook (4) comprises a snap-in element (5) for engagement in an opening extending through a wall in said bracket (3, 22, 23).

10. Pipe clamp, as set forth in claim 6, wherein said hook (4) comprises a snap-in element (5) for engagement in an opening extending through a wall in said bracket (3, 22, 23).
