The adjacent cells of the same fungal hypha brought into communication with each other using loops are known as a Clamp connection.
A clamp connection is a hook-like structure formed by growing hyphal cells of certain fungi. It is a characteristic feature of Basidiomycetes fungi.
It is created to ensure that each cell or segment of hypha separated by septa receives a set of differing nuclei, which are obtained through the mating of hyphae of differing sexual types.
It is used to maintain genetic variation within the hypha much like the mechanisms found in crozier (hook) during sexual reproduction.
