    • Jounce bumper (14) for mounting in a vehicle suspension system comprising a shock absorber with a cylinder and a slidable piston rod (12), the jounce bumper (14) including an elastically compressible bumper portion (24), a mounting portion (18) and an axially extending central bore (15) positionable around the piston rod. The mounting portion (18) comprises a plurality of flexible locking legs (26) configured for insertion through an orifice (32) of a structural element (16) of the suspension system, the flexible locking legs comprising locking protrusions (36) with retaining shoulders (39) configured to engage an edge (33) of the orifice in a locked position. The locking legs have radially inwardly directed cam protrusions (38) configured to be engaged by the piston rod and are movable from an intermediate position after insertion through the structural element orifice to a locked position after insertion of the piston rod through the jounce bumper central bore.
