FIELD: drilling rods or pipes, particularly safety devices for cable lines, which supply power to submersible electrical centrifugal pump motors used for oil, gas and other formation fluid production. ^ SUBSTANCE: device comprises body with longitudinal slot for cable receiving, as well as upper and lower fixing clips. The fixing clips are made of resilient material and are connected to the body by means of longitudinal ribs and depressions. The ribs are made on upper and lower body parts and extend for the full length of clip connection to pipe. The clips are inclined with respect to cylindrical body generatrix. Depressions are made in fixing clips and extend for the full lengths thereof so that the depressions are inclined at an angle equal to that of ribs. Fixing boss rows are formed in upper and lower body parts. Fixing orifice rows to receive bosses are created in fixing clips. Boss and orifice rows are at an angle equal to that of ribs. ^ EFFECT: simplified device structure, decreased labor inputs for device production and increased reliability of device body connection to flow string. ^ 3 cl, 2 dwg |
