Title: PIPE SLEEVE AND BALL JOINT COUPLING FOR CONNECTING PIPES
Abstract:
The invention relates to a pipe sleeve (30) for a ball joint coupling (10), comprising: an outer contour that is spherical at least in sections, and a pipe receptacle (32) delimited at the end by a pipe stop (33); wherein the pipe sleeve (30) can be coupled to a female pipe coupling device (20), said device having an inner contour that is spherical in sections, for coupling a pipe that can be received in the pipe receptacle (32) to the female pipe coupling device (20) in a hinged fashion. In order to be able to more easily detach a pipe wedged in the pipe sleeve (30), it is provided according to the invention that the pipe stop (33) be made up of at least two stop sections (34), which radially protrude from an inner wall (35) of the pipe sleeve (30). This allows access to an end side of the pipe between the stop sections (34) and the wedging can be easily detached.
