ABSTRACT:
A cable bushing device is used to pass an electrical cable through, in particular, two adjacent housings which are explosion and/or flame-proof. The cable bushing device includes a sleeve-like external body which can be inserted by the opposite first and second end sections into corresponding housing bores. Furthermore, the device has an insert inserted into an axial opening of the external body for retaining the electrical cables passed through the device and a fixing device for fastening the device to at least one housing. To improve a cable bushing device of this nature such that the assembly is simplified while retaining all the positive properties with regard to explosion and/or flame-proof protection and at the same time wider tolerances are possible in the manufacture of the housing bore, the fixing device has on the first end section an external thread formed to match an internal thread of the corresponding housing bore, a mounting nut which can be screwed onto the first end section and a limit-stop element assigned to the second end section and which essentially protrudes radially outwards.
