There are some notes from DG about L'Hotellier couplings (01/89 and Nov 30th 1992), which refer to the using spring pins and then the certification of sleeves to lock the coupling instead of the spring pins. I'm not old enough to know, but it would appear that in about 1/86, the spring pins appeared and perhaps spring pins were not used on L'Hotelliers before then. The note about sleeves is from 1992 and appears to allow sleeves instead of the pins but also says "the sleeves should be replaced every two years to provide adequate clamping force." It may be the DG are referring to these different types.
