Fastenings
First Claim
1. A fastener comprising a first component and a second component, the two components having a first released state and a second engaged state, wherein a portion of the first component is deformed relative to the remainder of the first component during the transition from first to second state, the deformed portion returning towards its original position in the second state to retain the first and second components together, the first component comprising a body portion and one or more dependant arm portions, the body portion having an inserted end and a non-inserted end, the one or more arm portions depending from the inserted end of the body portion inserted into the second component to provide a gap into which the one or more arm portions can be deformed, the gap extending from a lead end adjacent the inserted end of the body portion to a non-lead end, and the first component being provided with a grip portion on each arm portion, the grip portions surrounding the body portion to overhang a non-lead end portion of the gap between the arm portions and the body portion.

Abstract
A releasable fastener formed of a first, male (2), and second female component (4) is provided. Deformable arms (18) on the male component (2) extend back from the lead edge (14) of the body portion of the male component which is inserted into the female. Wedges (24) on the arms lock in apertures (40) in the second component (4). The gap between the arms (18) and the body portion is closed off by an end cap and grip portions on the arms to prevent trapping of fingers. The fastener is particularly suited to attaching nursery items, such as parasols, to nursery equipment such as pushchairs.
