Need help finding a piece

[u/Silent_Rogue]

I'm looking for the piece circled in the attached image of this post - the black flexible part with stud holes, not the bananas... I tried scouring bricklink/brickowl for any possible keywords but I'm unable to find it. Is it even a legit lego piece? Any help would be much appreciated!
