ABSTRACT:
A push-in coupling for pipes contains a sleeve body (2) and a holding means, especially with a clamping body (6), for connecting a pipe end (3, 4) to the sleeve body (2). This push-in coupling permits proper handling with little effort during assembly, and insofar as possible prevents the danger of faulty assembly. A sliding body (50) is disposed within the sleeve body (2), the sliding body (50) being made independently of the holding means. The sliding body (50) contains a striker (52) which upon insertion of the pipe end (3, 4) is pushed over an edge (60), and upon reaching a given depth of insertion of the pipe end (3, 4) strikes against a surface (62) producing a detectable signal such as an acoustical signal and/or a vibration signal.
