<p>Coupling device with hinged retaining catches made up basically of two concentric cylindrical parts (1, 9), the inner one of which extends frontally by means of clamping catches (2) provided on their inner face with retention toothing (3), these catches (2) being joined to the cylindrical body (1) of which they form a part, by hinges (4) which are integrated through the thinning of the actual material of which they are made, thereby offering said catches (2) the possibility of swivelling although with a constant tendency to separate in relation to the longitudinal axis of the cylindrical body of which they form a part. </p> |
