Abstract: A connection fitting (1) for attaching tubes, corrugated hoses, pipes, cables or other oblong bodies (2), in an opening or hole (3) of a wall (4), of a housing is provided. In this, the connection fitting (1) has an attachment projection (5) that can be anchored in the opening (3) and has retaining projections (8) located on abutment contact studs (7) formed by axial slots (6) that project radially outwardly across from a constriction. The abutment contact studs (7) and their retaining projections (8) are designed such that they have only a part of their retaining effect after insertion of the attachment projection (5) into the opening (3), i.e. they can be moved out of the opening (3) under a loading opposite to the insertion direction.
