In the case of a plastic screw union for entry and bushing, sealing and strain relief of cables, leads or the like, which consists of an intermediate connecting stub with a sealing body and cap nut and in the case of which clamping tongues are arranged coaxially on the hollow cylindrical intermediate connecting stub such that, during rotation of the cap nut of the sealing bodies, they press against the inserted cable, it is proposed to fit latching tabs, which project on to the other part, to the cap nut or intermediate connecting stub, preferably distributed uniformly around the circumference, so that preliminary fixing between the cap nut and the intermediate connecting stub is possible just by pushing on. In this case, the latching tabs form a type of elastic preliminary thread, from whose locking position further screwing on of the cap nut is directly possible. Furthermore, raised holding ribs are arranged on the inner surfaces of the clamping tongues which form an annular assembly, which holding ribs fix the sealing body in a preliminary manner while the latter is being inserted. This also serves to simplify preliminary assembly.
