Claim Text:
1. A plug connector for providing an electrical connection with a counter piece, the plug connector comprising: a housing in which contacts are supported in a front portion of the housing that is in front of the housing relative to a plug in direction of the plug connector into the counter piece wherein the contacts are connectable with a cable which is run out of a rear portion of the housing that is in a rear of the housing relative to the plug in direction of the plug connector into the counter piece; a securing sleeve which is supported on the housing so that it is rotatable and provides a securing screw connection for a plug connection between the plug connector and the counter piece, wherein an axial section of the housing and an axial section of the securing sleeve enter a form locking engagement at least at an end of a movement of the securing screw connection, wherein the form locking engagement provides vibration protection for the plug connection; and an elastic seal which secures the plug connection against contaminants, wherein a first locking profile is formed along an outer circumference of the axial section of the housing, wherein the first locking profile includes at least one first protrusion and at least one first recess, wherein a second locking profile is formed along an inner circumference of the axial section of the securing sleeve, wherein the second locking profile includes at least one second protrusion and at least one second recess, wherein the securing sleeve is supported on the housing so that the securing sleeve has radial movability relative to the housing, wherein a radial gap between the housing and the securing sleeve enables the radial movability of the securing sleeve and enables a radial rise of the at least one first protrusion above the at least one second protrusion when the at least one first protrusion and the at least one second protrusion contact each other during the movement of the securing screw connection, and wherein the elastic seal acts in a resetting manner against the radial rise.
