Potential and kinetic energy absorbing device for e.g. cable fixation stud, has male unit with teeth stopped and deformed against rim of opening for limiting or blocking relative sliding of male and female units subjected to traction force

摘要

The device (1) has a male unit (12) e.g. tab, extended into an opening delimited by a female unit (13) e.g. case, where the male and female units respectively comprise rings (121, 131). The units cooperate and slide with respect to each other at the level of the opening due to traction force applied at one of the units. The male unit has teeth (122) stopped and deformed against a rim of the opening for limiting or blocking relative sliding of the units subjected to the traction force.
