A few reserve parachute deployment handles on the following Supair harnesses had a manufacturing defect: SKYPPER, EVO XC2, SHAMANE and SHAMANE FR. If you have one of these harnesses then you should download, read and act upon the full safety warning dated 15/04/2014 (see download link below).
If you think your reserve handle is one of the defective ones then you should contact the dealer you purchased your harness from to arrange for a replacement. Otherwise you can buy a new reserve handle.
Kudos once again to Supair for being proactive about issuing safety notices!
