Various embodiments of a device for gripping elongated objects, such as electrical cords, are disclosed. The device comprises a one-piece, generally C-shaped ring member formed of at least two arcuate ring sections. The sections are hinged together to open and close in directions substantially normal to the longitudinal axis of the object encompassed by the grip. The ring sections have external camming surfaces which engage interior camming surfaces formed in a threaded nut with relatively low friction so that the ring sections are cammed inwardly to impart inwardly directed compressive forces to the object as the nut is tightened. The ring may be used to transmit axially directed forces produced by tightening the nut to a compressible sealing grommet encompassing the object. In such a case, the end of the section leading in the direction of nut rotation is inclined with respect to the longitudinal axis of the object to facilitate closing the ring about the object.
