Pipe coupling with improved tensioning system

A pipe coupling comprising:

• a tubular casing, having a longitudinal gap between a first free end and a second free end, for fitting around a pipe;
• and
• a tensioning system for tightening the casing around an outer surface of the pipe, the system comprising:
• at least one fastener having a first end and a second end, for tightening the casing around the pipe;
• a first member, coupled to the first free end of the casing, configured to engage with the first end of the or each fastener;
• and
• a second member, slidably coupled to the second free end of the casing, configured to engage with the second end of the or each fastener, the second member being longitudinally slidable from a first position, in which the or each fastener is free to move radially out of engagement with said second member, to a second position in which the or each fastener is in retained engagement with said second member, wherein the tensioning system further comprises a tubular portion, coupled to the second free end of the casing, having at least one transverse slot, the or each slot configured to receive a respective fastener, the second member being configured to slide within said tubular portion from the first position to the second position.
