ABSTRACT:
A conical guide for mounting on a coupling pin of an implement or the like which can be coupled to a three-point connection of a tractor may comprise a semi-conical member or a complete conical member divided to form two semi-conical members. The single semi-conical member is positioned about the coupling pin and has a clamp also positioned about the coupling pin so that the clamp and semi-conical member completely enclose the pin and are secured against axial displacement on the coupling pin by radially inwardly directed projections received within a notch in the pin. With a full conical member one of the semi-conical guide members functions as a clamp.
