Known locking and sealing electrical plug couplings contained locking claws and radially acting sealing rings or O-rings. These known devices had orhobliche llachtoilo. The construction with Yorriogelungßklauo was expensive and not easy to operate. The O-rings or sealing rings caused sticking that made it difficult

According to the invention, this is achieved in that the plug and the coupling piece interacting with the plug have cylindrical, telescopically interacting parts made of flexible plastic material, one of which. is i of these pieces with an annular retaining edge and the other piece having an annular, co-operating retaining groove formed "· wherein the two interacting holding elements with relatively

Because no radial pressure was exerted or absorbed in front of the O-ring there is no need for this ring to swell.

The height of the retaining edge and the 'i'iofe of the lialtonut are not go big that they are pulling off the ropes from the sun make simple porn difficult or possibly even impossible to create could. This means that the Ilintorsehnoidungen in the IOrms for the production of the connector and the female part are not so large that the formed bodies cannot be peeled off without any difficulty. The location of the 0-ilinges and the axial forces exerted or to be absorbed by it create an effective seal without any adverse effect on assembling or disassembling the coupling parts, even if the O-Iling is bulging or dusty should be.
