What is this used for? I can't understand at all. I have already met many times on cables, but I don’t see the point in this nozzle. Is that additional protection of the tongue, maybe.

Answer 1

I have already met many times on cables, but I don’t see the point in this nozzle.

Similarly - for me they are more of a hindrance than a help.
Connectors with such caps become very INCONVENIENT to remove - the cap prevents you from pressing on the antennae, the width of the connector increases - in the switch the connectors are right next to each other.
I recently bought patch cords of this design
. Here, on the contrary, it becomes more convenient to press the antennae. The mustache protection function is retained, the width does not increase.

Answer 2

I heard a hypothesis that rubber caps are needed in order not to spoil the connector, in the process of pulling the cable through the jungle. If there is no gum, then the antennae clings and breaks off. If there is an elastic band, then it cannot catch on.
(Although it seems that it is easier to just pull the cable and then crimp it).
