Pipe connectors and system with shell elements

The invention relates to a pipe connector for sealingly connecting to a pipe end, with a base body comprising a receptacle (4) for a pipe end, wherein the base body along the circumference of the receptacle (4) at least two shell elements (6a, 6b, 6c), wherein the shell elements (6a, 6b, 6c) at the circumferential ends of connecting portions (8a, 8a ', 8a' ', 8b, 8b', 8c '; 8c' '), said connecting means (10, 10') are provided, which for a compound of the shell elements (6a, 6b, 6c) to respectively associated connection portions (8a, 8a ', 8a' ', 8b, 8b', 8c '; 8c' ') are arranged. The object is to provide a pipe connector (2), with which the disadvantages can be avoided in the prior art and in particular the tubular connector (2) also in confined spaces easy to install and is suitable for laying in the ground, is achieved in that at least two associated connecting portions (8a, 8a ', 8a' ', 8b, 8b', 8c '; 8c' ') has a profiled neck area (16a, 16a', 16b, 16b ', 16c) for pressing with a pressing tool (32 ), so that the shell elements (6a, 6b, 6c) can be brought into a compressed state, and that the connecting means (10, 10 ', 12a, 12a', 12b, 12b ', 12c, 14) (for the connecting portions 8a , 8a ', 8a' ', 8b, 8b', 8c '; 8c' ') to the neck area (16a, 16a', 16b, 16b ', 16c) is adapted to the shell elements (6a, 6b, 6c) in to fix the compressed state. Next, a system and method for connecting a pipe connector to a pipe end and a use is to be specified.
