Two components, for example, conveyors, are interconnected by the intermediary of a connecting portion. The component connected to the connecting portion is shiftable along an alongate opening in the other component. The elongate opening is closable by means of a flexible web length which extends in the longitudinal direction of the elongate opening and in a loop about the connecting portion of the movable component. The connecting portion has guide means for successive lifting-out and laying of the web length respectively away from and towards the elongate opening on shifting of the connecting portion therealong.
