<p>The quick connection (1 ) allows fastening a tool (X1 ), (X2) to the lifter arm (S) of an operating machine (M) and includes first and second joining means (10), (20), associated respectively to said lifter arm (S) and said tool (X1), (X2), aimed at being reciprocally engaged. The first joining means (10) includes a swivel head (13) that swivels between a raised position (A) and a lowered one (B), and a first gudgeon (15); the second joining means (20) include a shaped body (21) that defines a calibrated inlet opening (25) and support means (22). The swivel head (13), in raised position (A), enters the shaped body (21 ) through the opening (25), then it rotates to its lowered position (B), thus bringing the first gudgeon (15) in engagement with said support means (22). The shaped body (21 ) includes a stop (24) aimed at striking a winglet (18) of the swivel head (13) and at preventing the latter from going out in any succession of movements which are not inversely equal to those carried out for the introduction.</p> |
