ABSTRACT:
The apparatus comprises wedging members (12, 13) consisting of elastic metal strips folded into crenellations, and a wedging member cooperating with said members and consisting of a flat strip (14) provided with openings (20) having the same spacing as the crenellations of the wedging members (12, 13). The wedging members (12, 13) have outer support surfaces (16) and inner support surfaces (17) cooperating with the flat strip (14). In the unlocked position of the apparatus the surfaces (17) coincide with the openings (20). In the locked position the members (12, 13) are moved apart by the flat strip (14), which comes into contact with the support surfaces (17). Passage from one position to the other is achieved by longitudinal displacement of the flat strip (14). The apparatus can be used in particular as an antivibratory bar in a steam generator of a pressurized water nuclear reactor.
