An electrical connector 14 has a threaded nut 22 with teeth 26 around an inner surface. Recesses 30 between the teeth 26 have a shallow portion 32 and a steep portion 34. An adaptor 36 is fitted into one end of of conduit 50 and rotatably carries the nut 22. The adaptor has a pair of spring-biased balls 46 which are urged outwardly into the recesses 30 in the nut. The different slopes in the recess enable the nut 22 to be rotated in one direction on the adaptor 36 but require a greater force to rotate the nut in an uncoupling sense. |
