Buckle for connecting first and second straps

Abstract

A buckle for connecting first and second straps ( 6, 7 ) includes a buckle body ( 1 ) that has, with respect to the longitudinal direction ( 5 ) of the straps ( 6, 7 ) to be connected, left and right side parts ( 11, 12 ) and first and second cross bars ( 2, 3 ) extending between the left and right side parts ( 11, 12 ) transverse to the longitudinal direction ( 5 ) of the straps ( 6, 7 ) to be connected and the buckle body has a movable middle bar ( 4 ) that extends transverse to the longitudinal direction ( 5 ) of the straps ( 6, 7 ) to be connected and that is supported so that it can move relative to the left and right side parts ( 11, 12 ) in the longitudinal direction ( 5 ) of the straps ( 6, 7 ) to be connected. The middle bar ( 4 ) rests on resting bars ( 13 a, 13 b ) of the side parts ( 11, 12 ). A bent support bar ( 16 a, 16 b ) extends from each of the resting bars ( 13 a, 13 b ), wherein the support bars each have a section lying in front of the respective end faces of the middle bar ( 4 ) and a section with a cutout ( 19 a, 19 b ) into which the respective end of the middle bar ( 4 ) projects, wherein this section faces toward the resting bar ( 13 a, 13 b ) from which the support bar extends.
