Actually you can not define a connectior with a slot.
There is enhancment request for it. You can define rigid connector that faces( the bodies dont move), however the program does not show connector results forces.
i'm nto following the description but it sounds like you want to use a connector to get forces out quickly
but you want to know what connector works with a slot
the answer is none
you'll need to use contact and model the part and pull forces out manually based on displacement and stress
Thank you Jared, and Seckin.
I will replace the slot by a simple pin in the position I need to analyse.
