The invention relates to a hooking device with undercut coupling. The device in question comprises a cylindrical body for undercut coupling (10,20,30,40), which is coupled to a body to be hooked, the upper part of which is connected to a connection system (4) that allows the connection of the device to another system such as for example a transport system; the cylindrical body comprises a coupling part (10a,20a,30a,40a) that has a surface provided with undercuts, is securely connected to the connection system (4), and has a lateral surface that extends over an angle with an amplitude less than 180°; the cylindrical body further comprises a centring part (10b,20b,30b,40b) that has a smooth lateral surface and has a diameter equal to the diameter of the cylindrical body without its undercuts; the two parts of the body (10,20,30,40) are mutually separable by means of a translation that brings them from a working position, in which the two parts are joined together to form the body (10,20,30,40), to a position for insertion into the body to be hooked, in which the centring part is always external to the body to be hooked.
