1. In an irrigation system fast coupling for connecting two hoses, comprising:
- a first inner body and second outer body coaxial with respect to each other, the first and second bodies being partially slidable with respect to each other along a common longitudinal axis;
said first and second bodies being hollow along said longitudinal axis and being detachably locked together via reciprocally cooperative connecting and disconnecting means;
said second body being adapted to be connected to a male connector;
an elastic torus-shaped element housed inside the second body, said elastic element being adapted to lock said male connector;
an elastic compression element longitudinally located between said first and second bodies;
said elastic compression element being adapted both to instantaneously disconnect the male connector from the second body and easily release the first body from said second body;
said first and second bodies being detachably locked when the fast coupling is in an operative state.

Abstract
The invention relates to fast couplings for connecting hoses, particularly for domestic irrigation. A fast coupling is formed by a first body and a second body reciprocally connected by inserting first lugs projecting from the second body in first slots made on the first body. A male connector is locked inside the fast coupling by radially pressing an end of the male connector with a torus-shaped elastic element. Unlocking the second body from the first body causes the automatic ejection of the mail connector.
