Abstract
A karabiner comprises a C-shaped body having a male part composed of a central tab and of a terminal protuberance in the form of a cap, and a pivoting finger equipped with a female part having a first orifice for access to an internal recess for accommodation of the male part when the finger is closed. A second outlet orifice is arranged in the finger opposite the first orifice, to ensure removal of the mud to the outside, and self-cleaning of the locking zone inside the recess. The protuberance is arranged as a fixed piston bounding a compressible volume open on the side where the second orifice is situated.
