A coupling device for fluid lines includes a female part having an annular wall with an aperture, a locking arm with a cam, and a male part having an annular wall with an outside surface with a circumferential groove and defining a longitudinal channel extending into the groove. The male part can be inserted into and rotated within the female part. The locking arm has a cam, and can be rotated between a locked position in which the cam is in a locked position and an unlocked position in which the cam is in an unlocked position. When the cam is in either the locked or unlocked position, the cam engages the groove to retain the male part within the female part, unless the male part is rotationally positioned relative to the female part such that cam is aligned with the channel, in which case the male part is releasable from the female part. |
