A screw coupling which can be applied to surround a cable, a hose, a conduit or a conductor has a nipple with an externally threaded section adjacent an end section with axially parallel prongs whose width decreases in a direction away from the first section toward an end face of the end section. Those end portions of alternate prongs which are adjacent the end face are enlarged in the circumferential direction of the nipple to engage a cable or the like when the prongs are flexed toward the axis of the nipple by a cap nut a first portion of which mates with the first section of the nipple and a second portion of which flexes the prongs toward the axis of the nipple. The remaining prongs have enlarged portions which are remote from the end face and can form a ring in response to predetermined flexing of the prongs, the same as the enlarged end portions of the alternate prongs. An elastic cylindrical seal is or can be inserted into the end section of the nipple to sealingly engage a conduit, a hose, a conductor or a cable which is surrounded by the nipple when the nut is applied with requisite force to flex the prongs relative to the first section of the nipple.
A screw coupling, particularly for surrounding cables, hoses, conduits, conductors and like bodies, comprising a nipple including an externally threaded first annular section and a second annular section fast with said first section and having an end face remote from said first section, said second section including a set of flexible prongs having first end portions at said first section and second end portions at said end face, and slots alternating with said prongs, the width of said prongs as measured circumferentially of said second section decreasing in a direction from said first section toward said end face, and said second end portions being enlarged and extending circumferentially of said second section and transversely of the neighboring slots;
