ABSTRACT:
A coupling device for a dishwasher pump with a synchronous motor and external stator, comprising a first tang connected to the delivery tube of the pump, a second tang connected to the suitable pipeline of a washing tank and a connection mean part. The connection mean part comprises a frustum of cone-shaped section, intermediate between said first and second tang and a flexible annular lip formed between said second tang and the smallest base of the frustum of cone-shaped section. Advantageously, the external part of the frustum of cone-shaped section is reinforced with annular ribs.
