An end fitting for a flexible conduit 62 comprises a spigot 12 and a nut 50 whereby the end of the conduit is expanded over an external screw thread 28 and an external taper 36 of the spigot and held by an internal taper 60 in the bore of the nut which has an internal thread 55 at one end engaging with an external thread 26 of the spigot. The screw thread 28 of the spigot 12 is a left hand buttress thread and the conduit end may be screwed into engagement with the thread or pushed over the thread. The nut 50 and spigot 12 have flats on their outer surfaces and the spigot has a third screw thread 14 for attachment to an electrical enclosure. A shoulder 38 is provided on the spigot 12 to limit the amount of insertion of the conduit. Flat parallel portions 32, 34 are provided on the spigot 12, on either side of the screw thread 28, which act as moisture seals in conjunction with the conduit end pressed down by the nut 50. The spigot 12 has a recess (18), Fig. 1 (not shown), with a shoulder 16, which carries an 0-ring (20).
