A fan for steady mounting on a wall or the like is divided in two independent constructional units (10, 20) which by means of a quick coupling of the bayonet type (21a min , 21b min , 31a, 31b) and a couple of electrical terminal means (14, 24) may be readily assembled and disassembled, whereby dismounting for repair or exchange purposes is facilitated. |
