Plug-in coupling for coupling a hose onto a pipe

摘要

A plug-in coupling for coupling a hose (1) onto a pipe (4) has a sleeve (2) which is at least partially introduced into the hose (1), such that it bears against the inner side thereof, is plugged together coaxially with the end portion of the pipe (4) and exhibits largely axially extending, flexible retaining arms (7). The retaining arms (7) can each be brought into engagement with a retaining rib portion (9a) on the outer side of the pipe (4). The hose (1) is enclosed by a bracing means (3) which braces the hose wall between it and the sleeve (2). Arranged between the sleeve (2) and the pipe (4), in at least one annular groove (12), is a sealing ring (13). In order to achieve simple construction of the plug-in coupling, the annular groove (12) which receives the sealing ring (13) is formed by a corrugation (6) which belongs to the sleeve (2) and presses into the hose wall. <IMAGE>
