A phonograph pickup arm assembly in which one end of the arm is fitted with a quick-connect socket for receiving a cartridge shell. The socket is slotted and the cartridge shell includes a pin for insertion into the slot. The socket includes a tapered surface and a nut cooperates with the tapered surface to force a resiliently deformable portion of the socket into tight engagement with an embraced portion of the cartridge shell. |
