Abstract

A cap adapted to be detachably mounted to a camera lens, for example, comprises a locking member movable radially of the body of the cap, grooves formed in the body, and a spacer mounted to the locking member. The locking member has engaging legs, which are fitted in the grooves and can be resiliently deformed within spaces. After the locking member has been mounted to the body, the spacer occupies the spaces and prevents the deformation of the legs.
