The invention relates to a flower carrier for use as a flower stand (window-box) in order to receive flower-pots, of the type of that consisting of a container 1 having the general shape of a rectangular parallelepiped, the upper face 1a of which is open in order to allow flower-pots 2 to be placed on and/or removed from the bottom 1b of the container 1. This flower stand (window-box) is noteworthy in that the container 1 is equipped with a locking device preventing removal of a flower-pot 2 by an unauthorised person. This locking device, constituted by a means for partially closing the opening 1a of the container 1, is controlled by a locking member 5 triggered by the validation of an authorised element allowing only an authorised person to carry out the operations of placing the said flower-pots 2 into the container 1 and/or removing them therefrom. This means for partially closing the opening 1a is constituted by two angle sections 3 and 4 each in the form of an upside-down L, the bottom ends of the vertical branches 3a and 4a of which are mounted so as to articulate about two spindles 3' and 4' which are placed parallel to each other and to the two upper edges of the two longitudinal vertical walls 1c and 1d of the said container 1. Applications: locking of flower stands (window-boxes) installed in public places, preventing acts of vandalism and, more particularly, preventing acts of theft. <IMAGE>
