FIELD: construction. ^ SUBSTANCE: device comprises holder arranged with the possibility of fixation at one of two perpendicular surfaces. Holder has two clamp levers for facing section bar passing in longitudinal direction of facing section bar and protruding towards facing section bar. Facing section bar is arranged with the possibility of placement onto clamp levers by means of opposite elastic application of clamp levers to clamp surfaces of facing section bar. One of two clamp levers retains support lever bent towards facing section bar for other clamp lever. Support lever loaded in process of placement of facing section bar onto holder is arranged with the possibility of displacement in the following manner. Either from initial position that retains clamp levers in open position into position that releases clamp levers. Or from initial position for placement of facing section bar into clamp position, which opens clamp levers. ^ EFFECT: invention provides for high clamp force. ^ 3 cl, 12 dwg |
