Spring-loaded clamping connection for clamping electrical conductors (9) in a conductor
insertion direction (L), with a clamping spring (4) formed from a sheet
metal part, which has a root region (48), a clamping leg (43) projecting movably from the root region (48) with its free end section, and a contact leg (40, 41, 42) projecting from the root region (48) with edge ribs (40), wherein the free end of the clamping leg (43) opposite the root region (47) has a clamping edge (46), and the edge ribs (40) define a first recess (A1) for passing the
electrical conductor (9) to be clamped and lead to a base section (41) of the contact leg (40, 41, 42), wherein the clamping edge (46) is aligned adjacent to the base section (41) in a closed position of the clamping leg (43) and in an open position of the clamping leg (43) is displaced from the base section (41), characterized in that - a retaining element (5) is formed integrally with the sheet
metal part, - wherein the retaining element (5) is connected to the base section (41) of the mounting leg (40, 41, 42) by a retaining section (52) and has at least one locking web (51) which has a locking contour (50) on which the clamping leg (43) can be locked in the open position, - wherein the retaining element (5) has at least one release element (8) which extends from the retaining section (52) in the conductor
insertion direction (L) and is connected to a release section (80) oriented transversely to the conductor
insertion direction (L).
