To permit ready disassembly of thread sensing and thread brake elements from a yarn feed device, the thread sensing, thread guiding and thread brake elements are, selectively, secured to a separate attachment or housing which is connected to the holder by means of a slidable shoe-socket arrangement which, additionally, carries the contacts for the stop-motion system of the machine so that, depending on yarn being used on the machine and supplied by the device, the supply guide element can be suitably assembled to the machine without disassembly of the thread feeding devices including the thread supply drums as such; or the stop-motion switches coupled to stop-motion sensing elements can be individually maintained or replaced.
