A device (1) for mutually fixing a longitudinal carrier (3) to a bone fixation element (4), wherein the device consists of a three-dimensional body (5) which has a channel (6) that is open on one side, wherein the axis of the channel (7) receives the longitudinal carrier (3), and a bore hole (8) that extends crosswise in relation to the axis of the channel (7) through the body (5) and that is provided with a wall (10). At least one part of the bore wall (10) disposed between the channel (6) and the bore hole (8) is embodied as an elastic element (11) which can be pressed into the region of the channel (6) by introducing the bone fixation element (4) into the bore hole (8), such that a longitudinal carrier (3) arranged in the channel can be firmly clamped in a rotational and longitudinal manner by said elastic element (11).一種用於將具一骨固定元件(4)的縱向縱載體(3)作對側固定的裝置(1),其中該固定裝置(1)由一個三度空間體(5)構成,該三度空間體(5)有一開放通道(6)及一孔(8),該開放通道(6)具有通道軸(7),用於容納該縱載體(3),該孔(8)垂直於該通道軸(7)延伸且完全貫穿該三度空間體(5)且具有一孔壁(10),其中:該位於通道(6)與孔(8)之間的孔壁(10)設計成彈性元件(11)形式,該彈性元件可藉著將一骨固定元件(4)放入孔(8)中放到通道(6)的區域中而施壓,如此一個位在通道中的縱載體(3)可利用該彈性元件(11)夾緊以防止轉動及縱向移動。
