Abstract: A device for hanging a collared garment, includes a support to be inserted into and hold the garment, on either side of the collar, and a hook secured to the support. The support has a body which ends in two folding ends, the device having an element for retracting the hook into the body, and an element for extending the folding ends such as to extend the body when a pulling force is applied to the hook, in order for the device to change from a first, more compact planar position, in which the folding ends are folded against the body and the hook is in the retracted position, to a second position in which the hook and the folding ends are extended, allowing the garment to be hung when a pulling force is applied to the hook of the device previously arranged in the garment.
