Abstract
A catch comprising a plunger member and a guide member, the plunger member being able to reciprocate in the guide member, with a nose of the plunger member extending out of the guide member, each of the members being a single moulding of a plastics material, one or both members including one or more tongues which extend primarily in the direction of relative reciprocation of the members and are resiliently flexible transversely to that direction, each tongue engaging a cam or a tongue on the other member in such a manner that forces act on the tongues having components parallel to the direction of relative reciprocation of the members, in the sense which urges the members towards a limit of relative reciprocation at which the extension of the nose out of the guide member is greatest, and if the nose is displaced into the guide member and released, then the plunger member returns to the said limit.
