Abstract

A connecting system for detachably connecting first pipe end to second pipe end, wherein first pipe end has sealing cone facing toward the second pipe end and a shoulder section. The connecting system includes first clamping disk, surrounding first pipe end and arranged on that side of the shoulder section which is averted from sealing cone, second clamping disk, surrounding and connected to second pipe end, and a multiplicity of screws, detachably connecting first clamping disk to second clamping disk. That section of first clamping disk which surrounds first pipe end is in the form of a separate circular disk ring which is detachably connected to the rest of the clamping disk, wherein the circular disk ring has multiple separate circular disk ring parts, and wherein the outer diameter of the circular disk ring is greater than the diameter of the shoulder section provided on the first pipe end.

First claim

1 .- 9 . (canceled)

10 . A connecting system comprising:
a first pipe end and a second pipe end, both of which are provided for realizing a detachable connection, wherein the first pipe end comprises a sealing cone which faces the second pipe end and said first pipe end is inserted with the sealing cone in a concentric manner into the second pipe end and comprises on its outside surface a circumferential shoulder portion, wherein the largest outside diameter of the sealing cone is greater than the outside diameter of the remaining first pipe end such that the shoulder portion is produced, a first clamping disk which surrounds the first pipe end in a flush manner and is arranged on the side of the shoulder portion remote from the sealing cone, a second clamping disk which surrounds the second pipe end and is connected to the same, and a plurality of screws which connect the first clamping disk to the second clamping disk so as to be detachable, wherein the portion of the first clamping disk which surrounds the first pipe end is realized as a separate circular disk ring which is detachably connected to the remaining clamping disk, wherein the circular disk ring includes several separate part circular disk rings, and wherein the outside diameter of the circular disk ring is greater than the diameter of the shoulder portion which is provided on the first pipe end.

11 . The connecting system as claimed in claim 10 ,
wherein the screws comprise expansion screws.

12 . The connecting system as claimed in claim 10 ,
wherein the screws are distributed uniformly along the circumference of the pipe ends.

13 . The connecting system as claimed in claim 10 ,
wherein the screws comprise an inner drive.

14 . The connecting system as claimed in claim 10 ,
wherein the screws include wedge lock washers.

15 . The connecting system as claimed in claim 10 ,
wherein the heads of the screws are arranged on the first circular disk and extend above the circular disk ring.

16 . The connecting system as claimed in claim 10 ,
wherein the contact surface between the circular disk ring and the remaining clamping disk is realized in a conical manner.

17 . The connecting system as claimed in claim 10 ,
wherein the contact surface between the circular disk ring and the remaining clamping disk comprises a ring-shaped support surface.

18 . The connecting system as claimed in claim 10 ,
wherein the contact surface between the circular disk ring and the remaining clamping disk comprises a thread.

19 . The connecting system as claimed in claim 10 ,
wherein the circular disk ring includes two separate semi-circular disk rings,
