Abstract
The invention relates to an apparatus for connecting a male part to a female part, of the type wherein the female part comprises a hole and a locking pin extending eccentrically across the hole. The male part comprises a cylindrical shank, the shank including a groove for engagement with the locking pin. The periphery of the shank includes a beveled portion of sufficient depth to allow a lower portion of the shank to pass the locking pin during insertion of the shank into the hole. The groove is disposed in such lower portion of the shank and is arranged to receive the locking pin in response to rotation of the shaft to prevent withdrawal of the shank.
