First Claim
1. A plug-in connection (1), in particular for fluid lines, comprising a part of the connection (2) to be inserted and a receiving part of the connection (3), between which a seal (10) can be clamped and which are able to be releasably connected to one another by flexible snap-in elements (7, 18) in a snap-in position, wherein the seal (10) is clampable between a front portion (4) of the part of the connection (2) to be inserted and an abutment (11) in the receiving part of the connection (3), wherein a circumference of the abutment is smaller than an outer circumference of the insertable part of the connection for compressing the seal in the axial direction of the connection upon insertion of the insertable part into the receiving part of the connection, and wherein the distance of the snap-in elements (7) of the part of the connection (2) to be inserted from the front portion (4) of the latter and of the snap-in elements (16) of the receiving part of the connection (3) from the seal (10) are dimensioned such that the snap-in position can be reached after slight axial compression of the flexible seal (10), and there is formed into said abutment (11) a groove (12), into which an axial continuation (13) of the seal (10) has been pushed for forming a labyrinth system, wherein said seal is fastened in an interior space of the receiving part of the connection, said seal is pushed in the radial direction, and in the axial direction against the abutment, and is secured against pulling out by radial form-fitting elements (14, 15).

Abstract
In a plug-in connection (1), in particular for fluid lines, which comprises a part of the connection (2) to be inserted and a receiving part of the connection (3), between which a seal (10) can be clamped and which are able to be releasably connected to one another by flexible snap-in elements (7, 18) in a snap-in position, the seal (10) can, be clamped between a front portion (4) of the part of the connection (2) to be inserted and an abutment (11) in the receiving part of the connection (3) and the distance of the snap-in elements (7) of the part of the connection (2) to be inserted from the front portion (4) of the latter is dimensioned such that the snap-in position is reached after slight axial compression, and if need be radial compression, of the flexible seal (10).

18. A plug-in connection, suitable for a fluid line, comprising an insertable part of the connection and a receiving part of the connection, between which a flexible seal is clamped and which are able to be releasably connected to one another by flexible snap-in elements in a snap-in position, wherein the seal is clamped between a front portion of the insertable part of the connection and a step in the receiving part of the connection, and wherein the distance of the snap-in elements of the insertable part of the connection from the front portion of the latter and of the snap-in elements of the receiving part of the connection from the seal are dimensioned such that the snap-in position can be reached after slight axial compression of the seal;
- and there is formed into said step (11) a groove (12), into which an axial annular continuation (13) of the seal (10) has been pushed for forming a labyrinth system.

19. A plug-in connection, suitable for a fluid line, comprising an insertable part of the connection and a receiving part of the connection, between which a flexible seal is clamped and which are able to be releasably connected to one another by flexible snap-in elements in a snap-in position, wherein the seal is clamped between a front portion of the insertable part of the connection and an abutment in the receiving part of the connection, wherein a circumference of the abutment is smaller than an outer circumference of the insertable part of the connection for compressing the seal in the axial direction of the connection upon insertion of the insertable part into the receiving part of the connection, and wherein the distance of the snap-in elements of the insertable part of the connection from the front portion of the latter and of the snap-in elements of the receiving part of the connection from the seal are dimensioned such that the snap-in position can be reached after slight axial compression of the seal;
- and
wherein said seal is fastened in an interior space of the receiving part of the connection, said seal is pushed by the front portion of the insertable part of the connection in the radial direction towards a circumferential surface of the receiving part of the connection and in the axial direction against the abutment of the receiving part of the connection, a groove is disposed in a radially extending wall of the abutment and radial form-fitting elements are disposed circumferentially of the seal in the receiving part of the connection, said seal being pushed into said groove and said form-fitting elements by the front portion of the insertable part of the connection.
