Possibly to be read as קלוטין, i.e., a pl. tant.. As shown by Amit Gvaryahu in Lesh 79 (2018):247ff., the Talmudic Hebrew equivalent of this expression refers to a special dispensation for excessive interest involved in overseas mercantile transactions, a usage probably influenced by (hardly a loanword!) the similar-sounding Latin term collocatum . One of these Semitic usages is obviously a play on the other, but which way the relationship goes is not clear.
