<p>A snap hook (snap shackle) 10 includes a body 12 in the shape of a C having a male part 18 composed of a central tongue 20 and of an end projection 22 in the form of a clevis, and a pivoting finger 14 equipped with a female part 24 having a first orifice 26 for access to an internal recess 28 for receiving the male part 18 when the finger 14 is closed. A second, escape, orifice 42 is formed in the finger 14 opposite the first orifice 26, in order to get the mud out, and ensure automatic cleaning of the locking zone inside the recess 28. The projection 22 is arranged like a stationary piston delimiting a sweepable volume open on the side of the second orifice 42. <IMAGE></p> |
