Abstract:
1. A combination of a plastic push-in fitting, a securing element and a plastic fluid line having an end section for sealed push-in connection to a mating element of complementary shape with the aid of said securing element which transmits axial forces, said plastic push-in fitting being molded on the end section coaxially by injection molding, and said end section protruding axially beyond the push-in fitting toward a distal end of the end section with a region, said combination comprising: a first circumferential groove formed into the end section in the region of which the push-in fitting is molded on with form-fitting penetration of the plastic of the push-in fitting into the first circumferential groove so that plastic of the plastic push-in filling completely fills the first circumferential groove from end to end, for axially affixing the push-in fitting to the end section, a second circumferential groove formed into the end section in the region which protrudes beyond the push-in fitting for receiving a sealing ring, said second circumferential groove being axially spaced from the first circumferential groove, and a third circumferential groove for receiving the securing element, said third circumferential groove being molded into the push-in fitting on an outer circumference thereof.
