Abstract
A strain relief arrangement (4) for a connecting cable (2) has a threaded pin (12), clamping tongues (13), a union nut (3), an enlarged diameter (10, 11) on the threaded pin (12), an extension (15), and a passage bore (25) for the connecting cable (2). By screwing of the union nut (3) onto the threaded pin (12), the clamping tongues (13) move inward and press against the connecting cable (2) for strain relief. The extension (15) is non-round, and an opening (6) of a carrier element (5) is complementary (7, 8) to the extension (15). An enlarged region (16) of the extension (15) has a circumferential groove (20) adjacent to the enlarged diameter (10, 11). The extension (15) can be introduced into the opening (6) of the carrier element (5) and can be fastened by rotation in the opening (6).
