ABSTRACT:
A plug-and-socket coupling temporarily attaches a handle to an implement. The plug has a cylindric plug body with an attachment device on one end for one of the handle or implement. A flange projects radially from the attachment-device end of the plug body and has an annular socket-engaging surface which is normal to the axis of the plug body. A spring strip projects from the flange annularly spaced from the plug body by the socket-engaging surface and parallel to the axis of the plug body. The socket of the coupling has a cylindric, tubular socket body with an attachment device on one end for the other of the handle or implement. The other end of the socket body is received between the plug body and its sprng strip when the plug and socket are coupled. A latching feature on the inside of the spring strip extending transversely to the axis of the plug body cooperates with a latching feature on the outside of the socket body for the temporary attachment. At least two axial notches of different lengths on at least one of the plug body and spring strip cooperate with at least two axial ribs extending radially from the socket body as anti-twisting structures, at least one of the ribs extending farther from the attachment-device end of the socket body than the latching feature thereof.
