A fitting for engagement with the outer surface of a cable has a sleeve with an external thread adjacent one of its ends and a nut having a complementary internal thread at one of its ends. The one end of the sleeve is of one piece with or supports a tubular clamping device with an annulus of axially parallel flexible prongs alternating with elongated slots. The nut has a ring-shaped internal deforming surface which flexes the prongs radially inwardly toward the axis of the clamping device, and toward the outer surface of a cable extending through the sleeve and the nut, when the sleeve is threaded into the nut. The prongs have relatively thick portions which are remote from the sleeve and relatively thin, and hence more readily flexible, portions between the thick portions and the sleeve. The thick portions of the prongs can bear directly against the outer surface of a cable or against a deformable tubular seal which is placed between the prongs and the cable. The internal and/or external surface of the seal is profiled to ensure predictable deformation regardless of the diameter of the cable.
