ABSTRACT:
The invention relates to an arrangement for forming a strain-relief connection which is safeguarded against axial displacement between an optical fibre cable containing strain-relief elements, at least one end of an optical waveguide which is closed by means of a sleeve projecting from the end portion of the cable, to a housing of a coupling device by means of a spacer sleeve which radially engages with both the housing and the end portion of the cable sheath. Excessive bending of the ends of the optical waveguide can be prevented when a covering sleeve clamping the strain-relief elements of the cable is connected to the end portion of the cable sheath, the covering sleeve including a longitudinal section having radially outwardly projecting form-coupling elevations and in that the spacer sleeve has a center portion which surrounds the ends of the optical waveguide with some spacing, and in that the spacer sleeve consists of two half-shells.
