A clip assembly configured to securely connect at least one tubular member to a structure, the clip assembly comprising: a base connected to one or more lateral walls; at least one tube cradle connected to one or both of the base and the one or more lateral walls, wherein the at least one tube cradle defines a tube-receiving channel configured to receive the at least one tubular member; and at least one tube-retaining locking arm configured to securely retain the at least one tubular member within the tube-receiving channel, wherein the at least one tube-retaining locking arm is configured to flex toward the one or more lateral walls as the at least one tubular member is inserted into the tube-receiving channel, and wherein the at least one tube- retaining locking arm securely connects to the one or more lateral walls when the at least one tubular member is received within the tube-receiving channel to securely retain the at least one tubular member within the tube-receiving channel, wherein the at least one tube-retaining locking arm comprises: an apex connected to the one or more lateral walls; a canted extension beam that downwardly angles from the apex toward a central axis in a central axial plane of the clip assembly also without a tubular member being inserted; and a tube-contacting beam extending back from the canted extension beam toward the one or more lateral walls, wherein the tube-contacting beam includes a distal catch configured to securely latch onto a protuberance of the one or more lateral walls, and characterized in that the at least one tube-retaining locking arm forms a triangular retainer with respect to the one or more lateral walls when the at least one tubular member is received within the tube-receiving channel and even without a tubular member being inserted. a base connected to one or more lateral walls; at least one tube cradle connected to one or both of the base and the one or more lateral walls, wherein the at least one tube cradle defines a tube-receiving channel configured to receive the at least one tubular member; and at least one tube-retaining locking arm configured to securely retain the at least one tubular member within the tube-receiving channel, wherein the at least one tube-retaining locking arm is configured to flex toward the one or more lateral walls as the at least one tubular member is inserted into the tube-receiving channel, and wherein the at least one tube- retaining locking arm securely connects to the one or more lateral walls when the at least one tubular member is received within the tube-receiving channel to securely retain the at least one tubular member within the tube-receiving channel, wherein the at least one tube-retaining locking arm comprises: an apex connected to the one or more lateral walls; a canted extension beam that downwardly angles from the apex toward a central axis in a central axial plane of the clip assembly also without a tubular member being inserted; and a tube-contacting beam extending back from the canted extension beam toward the one or more lateral walls, an apex connected to the one or more lateral walls; a canted extension beam that downwardly angles from the apex toward a central axis in a central axial plane of the clip assembly also without a tubular member being inserted; and a tube-contacting beam extending back from the canted extension beam toward the one or more lateral walls, wherein the tube-contacting beam includes a distal catch configured to securely latch onto a protuberance of the one or more lateral walls, and characterized in that the at least one tube-retaining locking arm forms a triangular retainer with respect to the one or more lateral walls when the at least one tubular member is received within the tube-receiving channel and even without a tubular member being inserted.
