A multipole connector for connecting a multipole-conductor cable comprising a cable receptacle and a connection piece, with the stranded conductors for axial contact of the free ends with assigned contact spikes of the connection piece being guided by axially parallel channels in the cable receptacle and being retained in the channels by clamping force by means of a coupling ring. The cable receptacle comprises a stranded-conductor mount for immovably fastening the stranded conductors and joining it, a terminal mounting, facing the connection piece. The stranded-conductor mount comprises a stationary fastening plate facing the terminal mounting, and a clamping plate movable in axial direction which when moving in the direction of the fastening plate, evenly and immovably clamps every stranded conductor against pulling movements. At least over the penetration length of the contact spikes into the channels, the terminal mounting is elastic in radial direction, in order to generate, by squeezing, even radial pressure at the circumference, for reliable contact, when the contact spikes are inserted, in all channels with matched channel diameter. This configuration makes it possible to construct a very short multipole connector where the number of stranded-conductor channels, and whether or not they are occupied, does not affect the clamping action. At the same time, clamping takes place in close proximity to the contact zone to prevent upsetting the stranded conductors in the channels. In addition, this configuration prevents flowing of the stranded-conductor insulation during insertion of the contact spikes through flexible channel walls on the one hand, and on the other hand permanent and even contact pressure on the compressed stranded conductors.
