Abstract: With the method of installing the pipe cable clamp with repeated clamping of the clamping strap (11), in the first phase of the installation, at the installation site, the helically wound clamping strap (11) gradually expands by the action of the expansion mechanism of the installation device by increasing its diameter until it adheres to the inner surface of the pipe over its entire outer circumference. The next phase of the installation consists in at least one re-tensioning of the clamping strap (11), which is performed by the repeated prestressing and releasing of springs (139) of the travel member (127) of the clamping lock (12) by the fastening mechanism of the installation device, always with fixing the previously reached clamping strap (11) clamping position. The tensioning cycle is repeated up to reaching the phase when the clamping strap can no longer be tensioned.
