FIELD: mechanical engineering.
SUBSTANCE: invention relates to a seal (1) of a plug-in coupling for guiding a medium of a pipeline of a drive motor, and this seal (1) of a plug-in coupling has an outer surface (5) for placing in the first part (11) of the coupling and an inner surface (7) for abutting the inserted into direction (16) of insertion into the first clutch part (11) of the second clutch portion (12). On the inner surface (7), micro-structuring (22) is performed with protruding structuring elements (23) to reduce the resistance of insertion of the second part (12) of the sleeve into the first part (11) of the sleeve.
EFFECT: invention provides a simplified connection process.
