Cable screw connection for passing a cable through a hole in a housing wall and fixing the cable with regard to the housing wall, comprising: - a clamp sleeve with a clamping section with ∘ a preferably cylindrical inner area which presents a sleeve internal diameter to hold the cable, and ∘ a flange section which is larger than a nominal diameter based on the hole, - a clamping element which is developed to be connected to the clamp sleeve in such a way that the sleeve internal diameter is hereby brought from a first diameter dimension at least via sections of the periphery of the inner area to a second diameter dimension which is smaller than the first diameter dimension; - an insert sleeve that can be connected to the clamp sleeve by means of connecting means, with - a base body which presents an outer area, the external diameter of which does not exceed a nominal diameter, - at least two retaining tongues (15, 16) distributed over the periphery of the outer area of the base body, each with a first centering area (15a, 16a) and an angled retaining area (15b, 16b) adjacent to the first centering area which extends outwards from the centering area, - wherein the retaining tongues (15, 16) are connected to the base body in a movable manner and elastically prestressed in such a way that each retaining tongue ∘ protrudes from a first position in which the retaining area (15b, 16b) protrudes into a larger external diameter than the nominal diameter and the centering area (15a, 16a) lies in an external diameter which is smaller than or equal to the nominal diameter, ∘ can be moved against the prestressing force caused by the elastically prestressed connection into a second position in which the retaining area (15b, 16b) and the centering area (15a, 16a) lie in an external diameter which is smaller than the nominal diameter, characterised in that the clamp sleeve and the insert sleeve are connected by means of a threaded connection, - whilst the clamp sleeve presents, at a second end opposite its first end, an internal thread with which an external thread of the insert sleeve interacts. - a clamp sleeve with a clamping section with ∘ a preferably cylindrical inner area which presents a sleeve internal diameter to hold the cable, and ∘ a flange section which is larger than a nominal diameter based on the hole, ∘ a preferably cylindrical inner area which presents a sleeve internal diameter to hold the cable, and ∘ a flange section which is larger than a nominal diameter based on the hole, - a clamping element which is developed to be connected to the clamp sleeve in such a way that the sleeve internal diameter is hereby brought from a first diameter dimension at least via sections of the periphery of the inner area to a second diameter dimension which is smaller than the first diameter dimension; - an insert sleeve that can be connected to the clamp sleeve by means of connecting means, with - a base body which presents an outer area, the external diameter of which does not exceed a nominal diameter, - at least two retaining tongues (15, 16) distributed over the periphery of the outer area of the base body, each with a first centering area (15a, 16a) and an angled retaining area (15b, 16b) adjacent to the first centering area which extends outwards from the centering area, - wherein the retaining tongues (15, 16) are connected to the base body in a movable manner and elastically prestressed in such a way that each retaining tongue ∘ protrudes from a first position in which the retaining area (15b, 16b) protrudes into a larger external diameter than the nominal diameter and the centering area (15a, 16a) lies in an external diameter which is smaller than or equal to the nominal diameter, ∘ can be moved against the prestressing force caused by the elastically prestressed connection into a second position in which the retaining area (15b, 16b) and the centering area (15a, 16a) lie in an external diameter which is smaller than the nominal diameter, characterised in that the clamp sleeve and the insert sleeve are connected by means of a threaded connection, ∘ protrudes from a first position in which the retaining area (15b, 16b) protrudes into a larger external diameter than the nominal diameter and the centering area (15a, 16a) lies in an external diameter which is smaller than or equal to the nominal diameter, ∘ can be moved against the prestressing force caused by the elastically prestressed connection into a second position in which the retaining area (15b, 16b) and the centering area (15a, 16a) lie in an external diameter which is smaller than the nominal diameter, - whilst the clamp sleeve presents, at a second end opposite its first end, an internal thread with which an external thread of the insert sleeve interacts.
