763,791. Conduits. BORRESEN, J., and PETTERSEN, G. N. Jan. 20, 1955 [June 22, 1954; Sept. 20, 1954], No. 1819/55. Class 36. A resilient, insulating strip 1 for a cable 4 has a generally U-shaped cross-section with inwardly-turned edges 3, the cable being inserted progressively from one end of the strip by pressure applied to overcome the resiliency of the strip. The base 2 of the strip may be formed with an internal groove 5 (Fig. 4) or an external T-shaped groove 5<SP>1</SP> (Fig. 5) for the reception of the heads of mounting-screws or brads 6. |
