An open nend - rotor spinning device (1) has a in a rotor housing (2) arranged spinning rotor (3), wherein the rotor housing (2) of a cover element (4) is covered, a pivoting mechanism (6) for opening and closing, as well as a locking device (7) for locking of the cover element (4). In the cover element (4) is a fiber feeding channel (8) and a thread withdrawal channel (9) is arranged. The pivoting means (6) and the locking device (7) are connected to one another. In the case of a method for operating an open nend - rotor spinning device (1), which is a during the spinning operation, in a rotor housing (2) running spinning rotor (3) is provided, the rotor housing (2) with a cover element (4) is closed or opened. The cover element (4), for opening or closing of the rotor housing (2) with a pivoting device (6) is pivoted and for locking of the cover element (4) with a locking device (7) locked. The pivoting means (6) and the locking device (7) are selectively connected to each other, or released from one another.n="31"
