ABSTRACT:
In a housing (3) of an attachment piece (1), at least one hollow core space (5) for receiving one end of a corrugated tube (2) is available. In this hollow core space (5) between the corrugated tube (2) and the housing (3), a sleeve (4) is disposed into which the end of the corrugated tube (2) is inserted. On this sleeve (4) elastic elements (15, 16) are present which are pressed toward an axis (29) of the attachment piece (1), through an outer ring (23) on the housing (3). At least one of the elastic elements (15, 16) is equipped with one positioning element (20) and a locking element (24), with these elements (20, 24) engaging an aperture (21) in the housing (3). The connection between corrugated tube (2) and housing (3) can only be broken with an auxiliary tool and is therefore protected against unintentional detachment.
