In the case of a locking device for a lock, especially a ring lock, comprising a connecting part (14) and a connecting part case (16) with a snap-in locking device (22, 24, 30), operated with a locking mechanism (32) a ratchet body (22) is accomodated in a guide passage (26) of a ratchet body guide element (24) oriented transversely to the direction of insertion of the connecting part (14) and is opposite a guide surface (30 at 31) at its side remote from the inserted connecting part (14). The guide surface (30), when the ratchet body guide element (24) is in a locking position, urges the ratchet body (22) behind a ratchet shoulder (20) of the connecting part (14) into an engagement position which prevents withdrawal of the connecting part (14). The ratchet body guide element (24) is movable into a first evasion position by means of the ratchet body (22) engaging the connecting part (14) during insertion of the latter, in which the ratchet body (22) is released to make an evasion movement by means of the guide surface (30 at 48). The ratchet body guide element (24) is rotatable when the locking mechanism (32) is twisted to a second evasion position in which the ratchet body (22) is released for an evasion movement allowing withdrawal of the connecting part (14) by means of the guide surfaces (30).
