Abstract:
1. A connection device for fluid lines comprising: a housing in which at least one housing recess is formed stepped in the longitudinal direction and merging at an inner end thereof with a fluid duct, an attachment means for attachment of a fluid line, said attachment means means being fixed in the housing recess and defining a passage opening rendering possible the plugging into position of a fluid line to be connected, and a seal and adapter component disposed in the housing recess, the seal and adapter component including a sealing ring portion being associated with said attachment means and an adapter ring portion, said sealing ring portion having an inner periphery matching the outline of the fluid line to be connected and being penetrated by the fluid line when connected, said sealing ring portion further having an outer periphery stepped in a radially outward direction with respect to a maximum outer periphery of said adapter ring portion, wherein a centering section of the housing recess is disposed axially within the housing from the attachment means, into which centering section the end section of the connected fluid line extends while simultaneously being transversely supported when inserted wherein said adapter ring portion is able to be inserted into the centering section for bridging over any radial intermediate space which dependent on the outer diameter of the fluid line is eventually present between the outer periphery of the line's end section and the inner periphery of the centering section, and wherein the sealing ring portion precedes the attachment means in an axially inward direction and makes sealing contact with a wall of the attachment means, and wherein the centering section adjoins a seal receiving section in an axially inward direction, said seal receiving section being bounded by a radial step formed in said housing and having a radial cross-section larger than a constant maximum cross-section of the centering section, said seal receiving section receiving said sealing ring portion.
