Munter hitch
An adjustable friction hitch from climbing, also called the Italian hitch; rope bondage glossaries use the name for a friction at crossing ropes, Japanese nodome.
In climbing, the Munter hitch is an adjustable friction knot made around a carabiner and used for belaying. According to Wikipedia, three Italian climbers developed it in the late 1950s as the mezzo barcaiolo, and the Swiss guide Werner Munter popularized it in the 1970s; it is also called the Italian hitch or HMS. Rope bondage borrowed the name for a friction that locks two crossing ropes or adds friction on uplines (Shibari Study; Rope365). Those glossaries treat it as the same knot as the crossing hitch, whereas Wikipedia says the two are often confused but differ. The Japanese name nodome comes from the shape of the kana の; sources write it の留め or の止め (Andrea Ropes; Shibari Study; Rope365).
