A polymer connecting piece for a clamping connector for tubes or pipes with peripheral ribs at outer end, abutment flange and tooth like projections on other side from flange

摘要

A polymer connecting piece (1) is disclosed for a clamping connector for pipes and/or tubes (2), made of a polymer material and comprising at least two pipe/tube connecting elements (3). At least one connection element (3) comprises a plug-in area (5) that is provided with peripheral ribs (4, 4a) and that is used to slide open the end of a pipe and/or tube (2a), to which respectively one flange projection (6) abuts. At least one tooth-shaped elevation (7) is arranged on the side of the flange projection (6) opposite the peripheral ribs (4, 4a). The disclosure also relates to a clamping connector for pipes and/or tubes (2) made of a polymer material and comprising the polymer connecting piece (1) and a sliding sleeve (10) that can be moved axially in relation to the pipe/tube axis. The polymer connecting piece (1) is stated to allow less material to be used in relation to the claimed connecting piece and prevents the flange projection (6) from being damaged during the production of said connection.
