A clip for connecting a sling to a lifting arm of a hoist, wherein the lifting arm is provided with at least one substantially mushroom-shaped fastening element which comprises a fastening pin and a fastening head integrally connected therewith, wherein the fastening head has a greater diameter than the fastening pin, wherein the clip is provided with: • a case with a body part in which a substantially keyhole-shaped recess (14, 16) is provided, wherein the substantially keyhole-shaped recess comprises a wide part and a narrow part, wherein the wide part has a dimension that is such that the fastening head is movable therethrough, and wherein the narrow part has a dimension that is such that the fastening head is not movable therethrough and the fastening pin is; • a locking member which is pivotably or slidably connected with the body part, wherein the locking member can assume a closed position and a release position; • a spring for biasing the locking member into the closed position; characterized by: • signaling means (22, 24; 22, 26-32) which are arranged for providing a signal from which it appears that the fastening element is positioned in the narrow part of the substantially keyhole-shaped recess (14, 16) in the right manner, wherein the signaling means (24; 26-32) comprise: ∼ a covering cap which is connected with the body part and which covers the narrow part of the substantially keyhole-shaped recess (14, 16) at least partly on a side of the body part; ∼ a signaling member which is slidably or pivotably connected with the body part, which is at least partly covered by the covering cap, which is provided with at least two differently colored areas (28, 28'), and which is slidable or pivotable from a first position to a second position and vice versa; ∼ spring means which urge the signaling member into a first position; ∼ at least one signaling recess in the covering cap or the body part which is associated with the differently colored areas (28, 28'); wherein the signaling member is in the first position when no fastening element is received in the narrow part of the substantially keyhole-shaped recess (14, 16) and wherein the signaling member is in the second position when the fastening element is received in the narrow part of the substantially keyhole-shaped recess (14, 16) in the right manner, wherein in the first position of the signaling member a first of the two differently colored areas (28, 28') is visible via the at least one signaling recess, wherein in the second position of the signaling member a second of the two differently colored areas (28, 28') is visible via the at least one signaling recess, wherein slidability or pivotability of the signaling member is independent of the slidability or pivotability of the locking member. • a case with a body part in which a substantially keyhole-shaped recess (14, 16) is provided, wherein the substantially keyhole-shaped recess comprises a wide part and a narrow part, wherein the wide part has a dimension that is such that the fastening head is movable therethrough, and wherein the narrow part has a dimension that is such that the fastening head is not movable therethrough and the fastening pin is; • a locking member which is pivotably or slidably connected with the body part, wherein the locking member can assume a closed position and a release position; • a spring for biasing the locking member into the closed position; • signaling means (22, 24; 22, 26-32) which are arranged for providing a signal from which it appears that the fastening element is positioned in the narrow part of the substantially keyhole-shaped recess (14, 16) in the right manner, wherein the signaling means (24; 26-32) comprise: ∼ a covering cap which is connected with the body part and which covers the narrow part of the substantially keyhole-shaped recess (14, 16) at least partly on a side of the body part; ∼ a signaling member which is slidably or pivotably connected with the body part, which is at least partly covered by the covering cap, which is provided with at least two differently colored areas (28, 28'), and which is slidable or pivotable from a first position to a second position and vice versa; ∼ spring means which urge the signaling member into a first position; ∼ at least one signaling recess in the covering cap or the body part which is associated with the differently colored areas (28, 28'); ∼ a covering cap which is connected with the body part and which covers the narrow part of the substantially keyhole-shaped recess (14, 16) at least partly on a side of the body part; ∼ a signaling member which is slidably or pivotably connected with the body part, which is at least partly covered by the covering cap, which is provided with at least two differently colored areas (28, 28'), and which is slidable or pivotable from a first position to a second position and vice versa; ∼ spring means which urge the signaling member into a first position; ∼ at least one signaling recess in the covering cap or the body part which is associated with the differently colored areas (28, 28');
