Abstract of the Disclosure A tool for rotation ring type barking machines comprises a swinging arm which is connected at one end via a screw connection with a holder on a shaft rotatably mounted in the rotor of the machine. The holder has two elongated grooves spaced apart by an intermediate ridge and adapted to accommodate two spaced-apart beads formed on the swinging arm. The two outer lateral faces defining the grooves are slop- ing in cross-section and converge toward one another at an angle slightly less than a corresponding angle of convergence between the outer lateral faces defin- ing said beads. Also the inner lateral faces of said beads and said ridge are sloping, and upon tightening of the screw connection at issue the beads are urged into the two grooves, the difference between said angles of convergence being gradually reduced toward zero until the inner bead faces come into contact with the lateral faces of the ridge, at which point the screw has been tightened with sufficient tensioning force.
