Buckle, lacing device and boot

Abstract

A buckle includes a base and a grip lug. The base underside can be placed against and fastened to a boot shell. The base upper side has at least one first receiving extension. In an engagement position a swivel element on the lug is latched at least in certain regions in the first receiving extension to form a swivelable first latching connection, to permit swiveling the lug in the engagement position from an open into a closed engagement position by the swivel element. At least one first latching extension is on the base upper side, and the lug has at least one latching element corresponding thereto. In the closed position, the latching element is latched at least in certain regions on the first latching extension to form a releasable second latching connection, to secure the lug against leaving the engagement position and against swiveling into the open position.
