<p>A connection system especially for water pipes has the pipe end (2 pushed onto a stub (12) and with an outer axially sliding sleeve (7) which slides over the outside of the pipe. The space (20) between the inner stub and the outer sleeve has a sealing insert which is displaced by inserting the pipe end. The displacement is monitored via a viewing port and can include a color change effect to monitor the positioning of the pipe end onto a stop.</p> |
