Abstract: An assembly is provided which is adapted to be used in attaching a secondary unit, such as a face protective device, to a primary unit, such as a safety helmet. The helmet is of rigid material and has the lower peripheral edge thereof provided with a flange forming a gutter or trough. A gap is formed in the flange so as to enable the assembly to be slidably mounted on and removed from the primary unit flange. The assembly includes a bracket having a base portion adapted to be in slidable supporting engagement with a segment of the exterior wall surface of the primary unit. The bracket also includes a first extension extending laterally from the base portion and slidably positioned within the trough at a predetermined location, and a second extension offset from said first extension and disposed outside the trough and in sliding engagement with the flange. The extensions coact with one another to resiliently grip the flange therebetween and retain the bracket in the predetermined location.
