temporary load securing device

Ah, I see now, got it.
As for posting another answer, well I feel you did the heavy lifting here, so I think you only need to reflect that nuance in your own answer and away you go!

As for the syntactical construction I used, my explanation for that is very simple: I placed “de fijación” at the end of the sentence to make clear that the term “fijación” refers to the “cable submarino” (see please my full proposal). If you write “dispositivo de fijación de carga temporal de cable submarino”, the reader might perhaps understand that “cable submarino” refers to the “carga temporal”, which is not the case here.

In response to your doubts and question:
“My sticking point is that I don't think it means "fijación" or "sujeción", plus I don't understand why Toni has placed "sujeción" at the end. I would have thought it would be "dispositivo de sujeción para cargas temporales [en un cable submarino]".
Robert, I think you have a point here. It might well be that “fijación”, “sujeción” is not the intended meaning by “securing”, but what you suggest instead, i.e. “protecting, supporting, or strengthening”. I must concede that I am not fully sure of my proposal (hence my middle confidence level) and I might have been misled by the French translation (dispositif de fixation), which I read before posting my own answer. This being said, I encourage you to post your suggestion, which might perhaps be on the right track in this case.

Cierto, no era fácil verlo ya que había que pinchar en otra pestaña.
De acuerdo también en lo de la colocación de fijación/sujeción en la frase, "dispositivo de sujeción para cargas temporales" sería también mi opción.

The link I posted is for the same patent as the one in the link you've just posted, or at least it talks about the same invention.

"(EN) A TEMPORARY LOAD SECURING DEVICE FOR AN ARMOURED HIGH VOLTAGE CABLE AND A METHOD FOR FACILITATING INSTALLATION-RELATED OPERATIONS OF AN ARMOURED HIGH VOLTAGE CABLE."

My sticking point is that I don't think it means "fijación" or "sujeción", plus I don't understand why Toni has placed "sujeción" at the end. I would have thought it would be "dispositivo de sujeción para cargas temporales [en un cable submarino]".

Yo la verdad no veo mucho en ese enlace que permita decantarse por una opción u otra (excepto la forma en la que se tradujo al francés, que a saber con qué rigor se hizo).
Sin embargo en este otro enlace sí se dan más explicaciones y parece que la opción de Toni es la correcta:

https://patents.google.com/patent/WO2017005278A1/en
... A TEMPORARY LOAD SECURING DEVICE FOR AN ARMOURED HIGH VOLTAGE CABLE AND A METHOD FOR FACILITATING INSTALLATION-RELATED OPERATIONS OF AN ARMOURED HIGH VOLTAGE CABLE .While performing the test, it is desirable to maintain the subsea power cable in a fixed position, in particular to restrict axial movement of the subsea power cable which may occur due to pulling forces from the weight of the majority of the subsea power cable submerged in the sea... When installing a subsea power cable in deep-water i.e. depths of 500-1500 m, or ultra deep-water i.e. depths starting at 1500 m, it may however be necessary to apply very high radial forces to the subsea power cable by means of the tensioners. The high radial forces may result in that the subsea power cable becomes damaged. A third situation which involves control of axial movement of a...

I think by "securing" they mean protecting, supporting, or strengthening. I posted a comment on Pablo's answer, but I was wrong so I removed it. I'm fairly sure now that, as Toni says, it means "carga temporal", because the device is designed to support subsea cables while they are under load, because when they are being reeled out from the spool, they undergo stress from the unsupported weight of the cable. So the idea is to clamp these devices to them so they won't break. Look:

So, I think the meaning in English is "device for supporting/bracing/bearing temporary loads".
