Abstract: A medical or organisation cart includes a clamping rail for attaching accessories. The cart is rectangular when viewed from above, with rounded corners. The cart includes corner profiles among which at least one is provided with a vertically extending undercut extending to a top surface or a worktop of the cart. The clamping rail has a tensioner, a counter hold element and a connection strap connecting the tensioner with the counter hold element and which the accessories may be attached to or hanged on. The tensioner may be positively connected with the corner profile at the vertical undercut, and the clamping rail may be fixedly attached to the cart and may be detached, both with the help of the tensioner. The clamping rail may be fixedly attached at any position of the vertical undercut and at a position of an adjacent corner profile corresponding to that first position.
