Strain relief for GPU cables

The strain relief serves as a reliable safety measure to prevent the cable from being accidentally pulled out of the connector receptacle on the aircraft. It can be easily attached to the connector – either using a hook or, on certain aircraft types such as the B737/B757, using a special plastic claw.

Main characteristics:

  • Secure hold thanks to the plastic claw, without damaging the aircraft
  • Quick and easy assembly
  • Stainless steel strap clamp and hook, corrosion-resistant, even when in contact with de-icing agents
  • Webbing with flame-retardant properties for increased safety

Assembly instructions

Distribution package


  •  Plastic claw and steel hook
  • Webbing with loop
  • 2 heat-shrink tubes

1. Prepare heat-shrink tubing


Slide the shorter heat-shrink tubing onto the cable at the point where the strain relief is to be mounted (usually about 1 metre from the plug). Then shrink the tubing using an industrial hot air gun. 

2. Attach belt with loop


Pass the strap through the loop and pull it tight on the heat-shrink-tubing.

3. Secure the loop


Slide the larger heat-shrink tubing over the loop and shrink it as well using the hot air gun. The loop is now securely fixed in place.

4. Strain relief ready for use


Pass the loose end of the strap through the stainless steel strap clamp. The strain relief is now ready for use.
