Abstract: A structure (10) comprising two shell parts (20, 30) which are connected to each other with at least one snap connection (21), wherein the two shell parts comprise, on the inner side, mutually complementary male and female snap means (25, 35) configured to form a snap connection (21 ), and wherein the two shell parts have complementarily configured abutment faces that abut on each other when the male and female snap means are interconnected (25, 35); wherein the male and female snap means (25, 35) comprise an external spiral-shaped protrusion (24) configured on the male snap means, and a thereto complementarily configured, internal, spiral-shaped protrusion (34) configured on the female snap means; and wherein the external spiral- shaped protrusion (24) on the male snap means (25) is configured such that it engages with the internal spiral-shaped protrusion (34) on the female snap means (35); and that the structure (10) comprises rotation-preventive means configured such that the two shell parts are unable to rotate relative to each other when the male and female snap means are interconnected to form at least one snap connection (21).

Abstract translation: 一种包括两个壳部件（20,30）的结构（10），所述两个壳体部件（20,30）通过至少一个卡扣连接件（21）彼此连接，其中所述两个外壳部件在内侧包括相互互补的凸形和凹形卡扣装置 （25,35），其构造成形成卡扣连接件（21），并且其中所述两个外壳部件具有互补配置的邻接面，所述邻接面在阳和阴卡扣装置相互连接时彼此抵接; 其中，所述阳型和阴型卡扣装置（25,35）包括构造在所述公扣式装置上的外螺旋状突起（24），以及构造在所述阴卡扣装置上的互补构造的内部螺旋形突起（34） ; 并且其中所述阳性卡扣装置（25）上的外部螺旋形突起（24）构造成使得其与所述阴型卡扣装置（35）上的内部螺旋形突起（34）接合; 并且所述结构（10）包括旋转防止装置，所述防旋转装置构造成使得当所述阳型和阴型卡扣装置互连以形成至少一个卡扣连接件（21）时，所述两个外壳部件不能相对于彼此旋转。
