Thank you Cory for the answer,
Your idea works also if I have, instead of a slice, only a portion of a slice 
(I cut slices portions thanks to the connectivity filter)?
In the image attached, I have created a connectivity (in blue) of a slice and a 
streamline in red that crosses it.

Best Regards,
Andrea

Andrea,

In fact, you can use the Slice filter itself to compute the intersection of 
streamlines with a plane. Just apply a Slice filter to your StreamTracer 
output, align the Slice with your desired plane, and you will get the 
intersection points.

See the attached image that shows stream tracer output, the plane widget from 
the Slice filter (red rectangle), and the intersection points depicted with 
blue spherical glyphs.

HTH,
Cory

Does anyone have an idea on how to deal with this problem?
Does Paraview have no tools to easily find a point of intersection between plan 
and line?

Subject: Find the intersection point between a connectivity and a stream tracer

Dear Users,
I need to find the intersection point between a connectivity surface (portion 
of a slice) and a stream tracer that runs through this.
I have tried the IntersectFragments it doesn’t work with stream tracer.
Someone of you have some suggestions?
Best regards,
Andrea
