ABSTRACT:
A screw coupling whose constituents are made of a plastic material and which comprises a nipple having an externally threaded section and flexible prongs extending from one end of the externally threaded section. The coupling further comprises a nut which can be rotated to move into mesh with the externally threaded section and to thereby deform the prongs toward the axis of the nipple and hence toward the external surface of a cable, a hose or another body which extends through aligned axial passages of the nipple and nut. Each prong has an elongated wedge-like main portion and a clamping portion which is fast with the free end of the main portion and extends from the main portion in the direction of rotation of the nut to move it into mesh with the externally threaded section. The clamping portions overlie the main portions of the neighboring prongs. The main portions of neighboring prongs are separated from each other by wedge-like slots. It is presently preferred to employ a set of identical prongs.
