For the insert part (10) is arranged an accommodation part (30) incorporating at least one free-supporting, forwardly directed leaf spring (32) clamped firmly to a rear area of the accommodation part. The leaf spring is formed with a widthwise extending forward-facing lock surface (34), which engages in a sprung manner with the insert part (10) backward-facing lock surface (18) for pliable locking of the insert part when it is inserted in the accommodation part. The lock surfaces (18,34) of the insert part and the accommodation part are concave and convex respectively, when observed towards the broad side. The lock surface of the leaf spring forms a front limitation of the leaf spring. The insert part has a rounded plate contour with an inwardly drawn root part (22). The insert part incorporates a relatively thicker front part (12) and a relatively thinner rear part (13) separated by the at least one lock surface. |
