An anti-vibration coupling system for a cover of an engine includes: a plastic pin with a semi-spherical head and reinforcement; a metal pin connected to the engine, with a threaded body and first head, with polygonal section, including a second head with circular section; a damping element with a first inlet end with a first semi-spherical recess for engagement with the head, and a second opposite end, with a second recess and a third recess, mutually coaxial, for engaging the first and second heads of the metal pin. The damping element includes, on the outer surface thereof, with an elasticizing ring, constituted by at least one circular loop that is suitably sized and positioned on the lateral surface in order to increase the elasticity of the damping element in a pre-established point. The damping element also includes through holes in order to further increase the elasticity thereof. 1. Anti-vibration coupling system for a cover of an internal combustion engine , adapted to allow the stable and reversible engagement of a cover to the respective internal combustion engine , damping any vibration , the system comprising:{'b': 1', '1', '12', '1', '15', '1', '1, 'a circular section plastic pin () projecting from the inner surface of said cover, consisting of the same thermoplastic polymer as said cover; said plastic pin () being provided with a head (), having semi-spherical shape or with spherical or pseudo-spherical cap, placed at the distal end of said plastic pin (), and at least one reinforcement (), placed at the proximal end of said plastic pin (), consisting of a hollow stiffening structure, adapted to rigidly but elastically constrain said plastic pin () to the respective cover;'}{'b': 2', '60', '1', '22', '23', '3', '2', '24', '23', '24, 'a metal pin () whose proximal end () is directly connected to said engine, at the position of the respective plastic pin (), provided with a threaded body () and a first head (), consisting of a projection adapted to ...
