摘要

The device has a contact holder (3), a strain relief unit and an insulating housing that is in the form of a coupler cover (1). The strain relief unit is removably insertable into the contact holder. The strain relief unit has an attachment mechanism comprising a groove that is aligned to a longitudinal center line. The attachment mechanism corresponds to the strain relief unit with a recess in the contact holder, where a dovetail guide is arranged in the recess. The strain relief unit has a clamping sleeve (22) and a center piece (23) that are formed as two components.
