more since it is appropriate to give the base elements themselves a particular minimum axial length so that a skew free fixing of these is possible prior to forming the welding seams as for the rest the pipe coupling may be so dimensioned that the coupling sleeve leaves an axial clearance between the annular flanges or rather the base elements when the device is closed this renders it possible to take up dimensional variations caused by manufacturing tolerances or possible deformations moreover which are produced by external action in the form described up to now the intermediate member of the pipe coupling proposed represents a separate component which may be lost as compared to the partial sleeves and the clamping lever closure which are all connected it is already known that the intermediate member already described in connection with the prior art may be connected by a radial fastening through the connecting bolt to the part shells and the clamping lever closure in corresponding manner this may be accomplished in the case of a pipe coupling in accordance with the invention in that a radial fastener or holder having a suitable aperture is provided on the coupling sleeve and the connecting bolt connecting the part shells passes through the aperture it is known that an intermediate member connected in this way to the.
