Abstract: The carabiner comprises a C-shaped body (1) and a gate (2) fitted movable between an open position and a closed position. The gate (2) is fitted rotatable with respect to the body (1). The gate (2) defines a cavity (2a) receiving a spring (4). A pusher (5) presses on the body (1). The spring (4) installed in the cavity (2a) of the gate (2) presses on the gate (2) and on the pusher (5) to bias the gate (2) to the closed position. The spring (4) is a coil spring extending along the longitudinal axis of the cavity (2a). The spring (4) and pusher (5) are fixedly mounted on one another to form a monolithic assembly.

Abstract: The descender comprises a handle and a cam that are movable between a securing position and a sliding position of the rope. The cam defines a first stop and a second pin. The handle has a first pin coming into contact with the first stop to form a first mechanical link and a second stop coming into contact with the second pin. Movement of the handle results in movement of the cam between the securing and sliding positions. In a threshold position of the handle, the first mechanical link is interrupted and the cam returns to the securing position. The second stop is movable with respect to the handle by means of a spring. When movement of the handle takes place, the second pin comes into contact with the second stop before the handle stresses a spring and reaches the threshold position.

Abstract: The invention relates to a carabiner including a metal body, and a gate rotatably assembled to a first end of the metal body between a closed position and an open position of the carabiner, the gate being in contact with a second end of the metal body when the carabiner is in closed position. The carabiner is provided with a separation bar fastened to the metal body and configured to define two distinct confinement areas. The bar is assembled by clipping onto the metal body at first and second opposite ends of the bar, the first end comprising a first fastener totally surrounding the metal body, and the second end comprising a second fastener totally surrounding the metal body. The separation bar being configured to authorize the opening of the gate when the first and second fasteners surround the metal body.

Abstract: The dowel comprises: i) a stem with, at one end, fastening means and, at the other end, an expansion cone; and ii) an expansion bushing mounted around a portion of the stem adjacent to the expansion cone and through which the expansion cone is intended to be moved so as to anchor the dowel into an anchoring hole of a supporting material. According to the invention, the expansion bushing is free of slits and drilled with expansion holes along an opening area of the bushing.

Abstract: A fastening system includes a base plate for receiving a fastening plug, the fastening plug having a shank and a head and the base plate includes a conduit for guiding and damping the shank of the plug. The base plate further includes a damping cup that is intended to house the head of the plug and the conduit following compression by the head of the plug, once the fastening plug has been driven through the base plate. The cup and the conduit are designed in such a manner that cooperation between the plug shank and the conduit causes the cup to at least partially cover the head of the plug when the plug is driven through the base plate.

Abstract: The fastening base plate includes a conduit for receiving the plug and support means intended to be applied to the component to be fastened. The plug comprises a shank and a head and the means for receiving the fastening plug comprise the conduit for guiding and damping the shank of the plug. The base plate moreover includes a damping cup in which the conduit, following compression by the head of the plug having a larger diameter than the conduit, and the head of the plug are intended to be housed once the plug has been driven through the base plate. The cup made of elastic material and the conduit are designed in such a manner that the cooperation between the plug shank and the conduit when the plug is driven through the base plate leads the cup to at least partially cover the head of the plug. The invention is particularly suitable for fastening wiring ducts.
