A support clamp for releasably mounting items on a support bar (19), comprising a locking body (1) and a support body (2) which under a mutual locking engagement are movable vertically in relation to each other and between which there is a locking means comprising a locking ball (13) which is vertically displacable in a guide bore (15) and an actuation ball (14) which co-operates with the locking ball (4) and which is horizontally movable in a guide bore (16) communicating with the guide bore (15) of the locking ball (13), and in which the actuation ball (14) is arranged to be actuated to a displacement in the guide bore (16) by an actuation groove (17, 18) in the support body (2), whereby the locking ball (13) when moving the support body (2) upwards in relation to the locking body (1) slides down in its guide bore (15) thereby releasing the support clamp, whereas the locking ball (13) when moving the support body (2) down in relation to the locking body (1) is forced upwards and partly out of the guide bore (15) actuated by the actuation ball (14) into a locking engagement with the lower surface of a support bar (19) or similar means. For this purpose the locking body (1) is formed with a horizontal through groove (4) which at the upper surface is formed as a locking bulge (5) adapted to be mounted in a corresponding portion (23; 23'; 23'') of the locking bar (19) whereas the groove (4) at the lower surface supports the ball locking means (13).
