摘要

The clamp has a support (1) e.g. wall bracket, comprising a chain locking device (2) having a fixed part (20) with a retaining unit (23) e.g. projecting lug, to retain a link of a chain. A movable arm (21) of the device pivots, relative to the fixed part, between an open position to permit access to the unit to place the link on the unit and a closed position. The arm bears against the fixed part to form a gap between the arm and the part for passage of the chain, in the closed position. A fastener fixes the arm on the part. A barrel (3) receives a portion of the chain locked by the device.
