摘要

The breakable device (20) comprises a frangible screw (22) extending along a longitudinal direction (X), the frangible screw (22) including: a first portion (30) having a first diameter and a second portion (32) having a second diameter (D2), and a frangible portion (36), extending between the first (30) and the second (32) portions in the longitudinal direction (X), and having a first length in the longitudinal direction (X). The breakable device (20) includes a sleeve (44) with an axisymmetrical general shape around a central axis, having, in the direction of the central axis, a second length greater than the first length, and comprising a first sleeve portion (46) having an inner diameter slightly greater than the first diameter and a second sleeve portion (48) having an inner diameter slightly greater than the second diameter.
