A lock component comprises a mounting plate (50) with apertures (51, 52) to receive screws to secure the plate in position. An intermediate resilient element (56) is mounted on the plate and has a peg (59) engaging a recess (53) on the plate to prevent rotation of the intermediate element. The intermediate element presents a collar (60) and projection (61) having an outer periphery configured to snugly engage an aperture (64) in an arm (62) which carries a lockable element (68). A connecting element (74) has a shaft (76) passing through a central aperture in the intermediate element (56), thus also extending through the aperture (64) in the arm (62). The shaft is connected to an aperture (55) formed in the mounting plate (50). The lockable element (68) has at least one degree of freedom of movement, which may be a rotational movement about the axis of the connecting element (74), or which may be a lateral movement. The lock component may be utilised with a locking arrangement so that when the lockable element (68) is engaged within the locking arrangement, the intermediate element (56) is deformed. The lock component may be used where it is difficult to provide exact tolerance, and may be used where it is desired for the lockable element to exert a resilient bias on the lock to minimise rattle.
