Fitting for producing a leaktight connection comprising a retaining element with contact surfaces

摘要

The invention relates to a fitting for producing a leaktight connection with a pipe end (4), having at least one pressing portion (6) which is designed for the insertion of a pipe end (4) and for pressing, having at least one sealing element (10) and having at least one retaining element (12), wherein the sealing element (10) and the retaining element (12) are arranged in the pressing portion (6), wherein the retaining element (12) is substantially annular, wherein the annular shape defines a circumferential direction and an axial direction and wherein the retaining element (12) has two ends (18, 18') with respect to the circumferential direction. The object of specifying a fitting with a retaining element (12) that has improved corrosion protection and can be produced in particular in a cost-effective manner is achieved in that the retaining element (12) has at each of the two ends (18, 18') at least one contact surface (20, 20', 20a, 20a', 20b, 20b') which extends at least partially in the circumferential direction and that the contact surfaces (20, 20', 20a, 20a', 20b, 20b') are designed to be brought into contact with one another upon pressing the pressing portion (6). The invention further relates to a system and a method for producing a leaktight connection between a fitting (2) according to the invention and a pipe end (4).
