Abstract

A coupling assembly for connecting two tubular elements, in particular ends of two tubes of an air-conditioning system, includes two inter-engaging locking parts which, for the purpose of achieving a locked position, can be rotated with respect to one another and can be displaced with respect to one another in the axial direction. The locking parts utilize a bayonet locking feature and include at least two sub-elements, the sub-elements being fixed in the radial direction by two inter-engaging sleeves.
