Central connectible yarn brake mechanism for doffed threads from a creel, including a profiled metal bar having at least one groove formed therein, stationary first brake elements being mutually spaced apart along the metal bar outside the groove and each being associated with one of the threads, a first device for individually connecting the first brake elements to the metal bar, movable second brake elements each being associated with one of the threads and being movable between a braking position in which the second brake elements are biased against a thread and against a respective one of the first brake elements and a detached position in which the second brake elements are lifted from a respective one of the first brake elements, bearings disposed on the metal bar in the groove, a central rotatable bar movable in the bearings in the groove, levers each being fastened to the rotatable bar, and a second device for individually connecting each of the levers to a respective one of the second brake elements for holding the second brake elements and moving the second brake elements between the braking and detached positions, at least one of the connecting means being an elastically deformable connection element.
