You are buying two pairs (so 4 x clips in total) of Blum 74.1103 Hinge Restrictors for 107 degree hinges.    

One restrictor should be installed on each hinge on a cupboard.

See the other picture on this listing to ensure you have the 107 degree hinge rather than the 110 degree hinge.  Note that there is no protrusion on the 107 degree hinge next to the deactivation switch - The metal is smooth.  Also note that the soft close part sits vertically when the cupboard is open (and the soft close activated)

If you instead have a 110 degree hinge then check out my following ebay item
