<p>A locking device for fixedly locking a chain in a substrate comprises a yoke (32) engaging with the chain and being insertable in the locking device and fixedly lockable therein by means of a locking cylinder (28). According to the invention, the locking device has a base portion (1) with a hole (22) intended for an anchorage bolt, and a hood (11) which outwardly encloses the locking device and which, together with the yoke (32), is fixedly lockable in the base portion (1) by means of the locking cylinder (28). The base portion (1) has undercut grooves (9, 10) with shoulders (17, 18) and foot portions (15, 16) which are bent at an angle to the hood and are insertable in the grooves to a position determined by the shoulders. Furthermore, the hood (11) and the yoke (32) have mutually cooperating surfaces (12, 13; and 36, 37), respectively) which, in the locked position of the yoke (11) on the locking device, prevent withdrawal of the hood (11). In its inserted position in the locking device, the shanks (34, 35) of the yoke (32) are supported against the inside of the hood (11) and against a guide portion (6, 7, 20, 21) which also serves as a back plate for a bolt bar (31) which engages in recesses (40, 41) in the shanks and thereby locks the yoke.</p> |
