Abstract: A quick connect/disconnect device and method for manually demountably attaching carrier bars to an endless train comprising a conveyor adapted for conveying pellet-like items in a pellet marking machine is disclosed. The device comprises an elongated shank with an enlarged head and a central bore coaxial therethrough. Radially oriented passages disposed adjacent to the end of the shank opposite the head house balls which extend outwardly beyond the outer surface of the shank when a plunger within the central bore is biased to its normal position. Moving the plunger against its biasing spring allows the balls to retract partially within the central bore, allowing the shank to be inserted into mounting holes in the carrier bar and receiving holes in the endless train. When mounted on the train the carrier bar and endless train are sandwiched between the enlarged head and the extended balls, the carrier bar being retained to the endless train thereby.
