Abstract
A cable grommet with tension or strain relief for the securement of cables in the aperture of a housing comprising two tubularly shaped and coaxially telescoped clamping portions being twistable towards each other, and the inner cross section of the outer portion, which is to be inserted into the aperture of the housing, deviates from the concentric circular cross section and the inner portion being coaxially inserted into the outer portion is divided, on one of its ends, by slots extending in axial direction over part of its length to form clamping jaws which on the outer side thereof, at least partly, are provided with circumferentially extending rising or tapering projections sliding on the inner wall of said outer portion and which when the two portions are twisted towards each other press the clamping jaws against the cable guided in said inner portion.
