In a two-part container having at one end a hole (29) through which wire from a reel housed in the container can be withdrawn, the two parts (1, 21) of the container are secured together by relative rotation of one with respect to the other, e. g. by a multistart screw thread. The parts carry a spring-loaded pawl and ratchet mechanism (4, 24) which permits relative rotation when the two parts are being secured together and which, when the two parts are fully engaged, prevents separation of the two parts by relative rotation in the opposite direction unless the spring-loaded pawl (24) is disengaged from the ratchet (4). |
