Abstract: A bead for releasably securing a glazing unit to a frame member, comprising a body having a first end and a second end, and a resiliently deformable member secured to the body and having a first finger extending from the body to a first end, and a second finger extending from the first finger to a second end. The first end of the body and the first end of the first finger are configured to engage with respective first and second ends of a frame member so as to secure the bead to the frame member. The second end of the body is configured to secure a glazing unit against an opposed seal of the frame member. The body comprises a first material having a first stiffness and the deformable member comprises a second material having a second stiffness less than the first stiffness.

Abstract: A frame connector for securing a first frame member to a second frame member, the frame connector comprising a first body having a first pair of arms extending along first and second axes from a origin mitre plane to respective free ends; a second body adjacent to the first body and having a contact surface and a second pair of arms extending from the origin mitre plane to respective free ends, and an actuator secured to the first body and arranged to apply a force to the contact surface in a first direction. The first and second axes are non-colinear and define a first plane. The first direction forms an acute angle to the first plane. The actuator is arranged to displace the first body relative to the second body in the first direction.

The first end of the body and the first end of the first finger are configured to engage with respective first and second ends of a frame member so as to secure the bead to the frame member. The second end of the body is configured to releasably secure a gasket in a first position so as to secure a glazing unit against an opposed end of the frame member.
