Removable plug-in connection for high-pressure lines

Abstract

A removable plug-in connection for high-pressure lines, in particular brake lines in the construction of motor vehicles. The connection includes a cylindrical receiving housing () with a central receiving chamber (), in addition to a tubular plug-in part, which is equipped with a peripheral retaining rib. An insertion side of the receiving housing () has an enlarged receiving chamber () in which several radially guided locking elements () can be retained, the elements being clamped in a direction of the interior by a retaining ring (). The locking elements () include two half-shells () that include retainer wedges () that point inwards, engaging behind the retaining rib () in a positive fit once the plug-in part () has been inserted. Each half-shell () has a projecting centering pin on one end face, the pin constituting an extension of the internal wall and engaging in a corresponding cavity on the opposing end face when the two half-shells () are assembled. Once the half-shells have been retained (), the front edge () of the wall () that surrounds the enlarged receiving chamber (') is bent inwards at an oblique angle to the axis of the receiving housing () until the retaining rib can pass through unhindered and the half-shells () are outwardly displaced when the plug-in part is inserted.
