摘要：A coupling arrangement (10) for coupling an injector (6) to a fluid supplycomprises a fuel connection (12) which is cup-shaped having a bottom portion and a sideportion, which is fixed to a pipe (8) of the fluid supply. A locking element (14) is cup-

shaped and comprises a rim (17), a bottom portion and a side portion and is coupled tothe fuel connection (12). At least a part of the side portions of the locking element (14)and of the fuel connection (12) form an overlapping area. An inner spring (18) is arrangedin the fuel connection (12) and is fixed to the bottom portion of the fuel connection (12)at an axial end of the inner spring (18). An outer spring (16) is arranged intermediate thepipe (8) and the locking element (14), the outer spring (16) having a larger diameter thanthe inner spring (18) and the outer spring (16) forcing the locking element (14) away fromthe pipe (8). At least one pin (26) of the fuel connection (12) is arranged in theoverlapping area at the fuel connection (12). At least one recess (28) is formed in thelocking element (14) and extends from the rim (17) of the locking element (14) towardsthe bottom portion of the locking element (14) and further at least partly parallel to thebottom portion of the locking element (14) and further towards the rim (17) of thelocking element (14) to a second end (32) of the recess (28) of the locking element (14).The second end (32) of the recess (28) of the locking element (14) takes in the pin (26) ofthe fuel connection (12).
