Abstract

A device for locking and unlocking by means of a wrench a plug or lid on a frame, notably of a manhole The present invention relates to a device for locking and unlocking by means of a wrench, a plug or lid on a frame, notably of a manhole. According to the invention, the bolt (8) is mounted and guided in translation in a casing (10) of the plug (1) and is held in its locking position by a pre-stressed coil compression spring (13) between the bolt (8) and a bottom wall (14) of the casing (10) , the bolt (8) comprising a transverse branch (16) on which an end (7) of the wrench (3) may act in order to displace the bolt (8) towards its position for unlocking the plug (1) from the frame. The invention finds application for road system equipment. Fig. 18
