Abstract
The connecting device comprises a connecting body (12) and at least one connecting piece (20) adapted for having plugged thereon the end portion (24) of the plastic tube (14) to be connected. The outer diameter of the connecting piece (20) is slightly larger than the inner diameter of the plastic tube (14). Prior to plugging the plastic tube (14) onto the connecting piece (20), a pressing sleeve (28) is shifted onto the plastic tube (14). The inner diameter of the pressing sleeve (28) is selected such that the pressing sleeve (28) can be pressed onto the end portion (24) of the plastic tube (14) plugged on the connecting piece (20). During this process, the plastic tube (14) is displaced in axial direction until its forward end is received in a receiving groove (46) annularly surrounding the connecting piece (20) and being open towards the plastic tube (14). The receiving groove (46) is inclined with respect to the axis ( 50) of the connecting body (12), with the annular diameter of the receiving groove (46) decreasing with increasing depth.
