■. ■ · Plug

The innovation relates to plugs, in particular isolating plugs for isolating distributors in telecommunications systems. It aims at 'one'. To create a plug that is absolutely stuck after being plugged in and can also be unintentionally touched, in particular Pull cord, not loosen.

To achieve this end it has already been suggested that the To provide plug with locking means. The aim of the innovation is to produce a particularly advantageous embodiment of a plug with blocking and suggests a plug advises a housing two shells, which laterally elongated like a corner

^: The housing of the plug consists of the shells 1 and 2. The shell 1 is designed to accommodate the required components. It contains recesses for receiving the locking springs 16, the locking levers 6 and the plate 13 carrying the contact elements 14, bearing pins 3 for the locking levers 6 and annular beads 4, through which the correct insertion of the carrier plate 13 for the contact elements 14 / is ensured. The bearing journals 3 and the annular beads.4 are formed in one piece with the shell. This also contains a recess for the introduction of the connecting cords 17. Because of this design of the shell, the proposed plug can be fitted very easily.
