Fitting for corrugated tube cable

A fitting for a coaxial corrugated tube cable whose corrugated tube (3) has an outer surface which is corrugated in an annular shape, having an abutment (6), which surrounds the corrugated tube (3), for a flanged rim, having a housing (10, 18) with a housing front part (18) in which an annular contact surface (27) for the flanged rim is constructed and which is opposite the abutment (6), and having a housing rear part (10) which surrounds the abutment (6) and can be clamped by screwing to the front part (18) and to the abutment (6), and having an inner conductor contact part (29) which is centred in the housing, and is insulated from the housing, by an insulator (30), the internal diameter of the contact surface (27) corresponding to the smallest internal diameter of the corrugated tube (3), and the abutment (6) having on its inside a section (8) which is matched to the contour of a trough of the corrugated tube (3) and extends in the trough onto the trough base, as far as or slightly beyond said trough base. The front part (18) and the rear part (10) of the housing are screwed to one another by means of a separate union nut (44).
