Abstract (en)
[origin: FR2904014A1] The device has a bolt (8) removably assembled and guided in translation in a housing (10) of a plug. A helical compression spring (13) that is interposed between the bolt and a base wall (14) of the housing maintains the bolt in a locked position. The bolt includes a transversal branch (16) on which an end (7) of a key (3) acts upon for displacing the bolt to an unlocking position of the plug of a frame. The bolt is made of a plastic material i.e. polyacetal.
