Gripping apparatus for restraining the gun barrel on an armored vehicle comprises a pair of gripping jaws pivotally supported within a housing and connected by a first pair of toggle links to a movable carriage within the housing such that the jaws are opened and closed upon movement of the carriage, a pair of locking members slidably carried on the carriage and adapted to enter apertures in the sides of the housing to lock the carriage at a predetermined location at which the jaws are closed and the toggle links of the first pair are in substantially a straight line relationship, and a second pair of toggle links connected to the locking member and to an actuator rod so as to enable the toggle links of the second pair to assume an over-center position upon the locking members being received in the apertures for positively locking the carriage in the predetermined location.
