Description

technical field

[0001] The invention relates to a releasable plug-in joint for inserting tubular inserts with peripheral ribs. Background technique

[0002] The invention relates to a releasable plug-in joint for inserting tubular inserts with peripheral ribs. The insert may be the end of a relatively rigid metal tube for a fuel line. However, the couplings can also be made, for example, of hard plastic or other commonly used injection-molded materials, and can be connected to hose lines or pipes in the usual manner.

[0003] In the existing plug-in joint, the insertion end of the receiving shell is integrally formed with the edge of the locking edge, and the edge of the locking edge has an inclined insertion surface in a circular arc shape, and the receiving shell and the locking edge are diametrically opposed on the inner wall of the receiving shell. The insertion end is designed with two mutually shaped and diametrically opposed openings forming a peripheral ring at the...
