Patent ID: 8678443

Claim:
A polymer connecting piece ( 1 ) for a clamping connector for pipes and/or tubes ( 2 ) made of a polymer material comprising at least two pipe/tube connecting elements ( 3 ), wherein at least one connecting element ( 3 ) includes a plug-in region ( 5 ) which is provided with peripheral ribs ( 4 , 4 a , 4 b ), for slidingly connecting to each of a pipe and/or tube end ( 2 a ) against which a flange projection ( 6 ) abuts, wherein a plurality of tooth-like projections ( 7 ) are disposed on the side of the flange projection ( 6 ) to create a support for a tool used for establishing a clamping connection, which are located opposite to the peripheral ribs ( 4 , 4 a , 4 b ), wherein a free space ( 8 ) is provided between the flange projection ( 6 ) and the tooth-like projections ( 7 ), wherein the plurality of tooth-like projections ( 7 ) are disposed so as to be distributed across a periphery of the polymer connecting piece ( 4 ) and wherein gaps are disposed between the individual tooth-like projections ( 7 ).
