Abstract
The invention relates to a connecting device having a first pipe connecting piece, a second pipe connecting piece and a securing part. The two pipe connecting pieces are adapted to be connected to one another in a releasable and fluid-tight manner by the securing part. The first pipe connecting piece has at least one recess on the outside, and the second pipe connecting piece has a collar and an outer piece of pipe, which between them form an annular space bounded on one side in the axial direction and which accommodates a sealing element. The outer piece of pipe has at least one aperture. The first pipe connecting piece is adapted to be introduced into the annular space. The securing part has at least one catch element, which can be inserted into an aperture, thereby entering a recess. A filter device with such a connecting device is also provided.
