• said plurality of hooks can comprise two hooks hinged to said main body so as to be diametrically opposed each other.
• elastic reaction of said second elastic means acting on said at least one pawl along said hinging axis can be higher than thrust along said hinging axis due to elastic reaction of said first elastic means acting on said at least one hook about said hinging axis so as to prevent rotation of said at least one hook with respect to said main body about said hinging axis by said first elastic means with said at least one pawl engaged within one of said grooves.
• said elastic reaction of said second elastic means acting on said at least one pawl along said hinging axis can be lower than thrust along said hinging axis generated by the action of a user manually rotating said at least one hook with respect to said main body about said hinging axis so as to permit opening and closure of said closing device.
• said first elastic means can comprise, for each one of said at least one hook, a pin spring fit on the pin defining hinging between said at least one hook and said main body, said pin spring having its arms respectively engaged within two cavities respectively realized by said main body and said at least one hook.
• said second elastic means can comprise a helicoidal spring housed within said seat and placed between said housing seat bottom and a thrusting surface defined by part of said at least one pawl opposed with respect to said lateral surface, said at least one pawl comprising an arm, sliding housed within said helicoidal spring to maintain alignment of said at least one pawl along said hinging axis.
• said closing device can comprise, for each one of said at least one hook, a mechanical stop surface defined by said main body to prevent too large rotations of said at least one hook when passing from said closure configuration to said opening configuration and vice versa.
• said blocking means can comprise a further groove, obtained on said lateral surface of said at least one hook between said at least two grooves, so as to permit blocking of said at least one hook in an intermediate configuration, between said opening configuration and said closure configuration.
