Connecting plug and socket with lamella basket

A socket comprises an annular socket part and a lamella basket at least partly disposed in the interior of the annular socket part. The lamella basket comprises a plurality of lamellae and an annular carrier strip located at the rear part of the lamella basket. Each of the lamellae has a first end and a second end, with the first end being firmly attached to, or integrally moulded with, the annular carrier strip and with the second end being implemented as a free end. The lamellae extend from the annular carrier strip towards the front end of the socket. The inner surface of the annular socket part comprises a bulge that: protrudes in a radially inward direction; and is configured for supporting the lamellae when the lamellae are resiliently deformed in a radially outward direction.
