| 摘要 |
The invention relates to a connection device (1) for pipe lines (2), comprising a connection element (6) that has a receiving opening (4) for a pipe line (2) to be inserted with a line end (2a), and a retainer element that is mounted within said receiving opening (4) in order to stop the inserted line end (2a) from being pulled out. Said retainer element is designed as a spring-elastic toothed ring (8) that has an outer circumferential region (8a) and a plurality of retainer teeth (8b) which are distributed across the circumference and which extend radially inwards and at an incline in the pipe insertion direction (X) and act force and/or form-fittingly against the line end (2a). Inside said connection element (6), the toothed ring (8) is mounted with its outer circumferential region (8a) having a limited axial movement play that is defined by contact sections (12, 14) on either side. At the transition region (15) between the outer circumferential region (8a) and the retainer teeth (8b), the toothed ring (8) interacts with a circumferential tilt edge (16) which is provided inside the connection element (6) such that as a result of said line end (2a) resting against the retainer teeth (8b) when it is inserted, the toothed ring (8) can first pivot in a rocking manner about the tilt edge (16) out of a position in which its outer circumferential region (8a) is pressed against the first, lower contact section (12) in the insertion direction (X), and until said outer circumferential region (8a) comes to rest against, and is supported on, the second, upper contact section (14) which lies axially opposite, the retainer teeth (8b) which project radially inwards above the tilt edge (16) being able to be elastically deformed by bending. |
