ABSTRACT:
A releasable coupling comprises a female component providing an open ended sleeve and a male component having a projection for insertion into this sleeve, said projection comprising an enlarged hook formation or detent connected by thinner resilient connecting members to the body of the male part. The form of the components is such that said projection can be inserted through said sleeve, the hook formation, on emerging from the end of the sleeve opposite that from which it was inserted springing resiliently, due to said connecting members, in a transverse direction perpendicular to the insertion direction to bring an abutment face on the hook formation into opposition with an abutment at the end of the sleeve opposite the end from which the said projection was inserted so that the components can thereafter be uncoupled only after displacing the hook formation in the direction opposite to said transverse direction.
The projection on the male component also includes a lug, independent of the resilient connecting members, which fits in the sleeve when the components are fully coupled and prevents gross transverse movement of the male component as whole relative to the female component when the components are fully coupled thus ensuring that only deliberate resilient displacement of the locking formation relative to the other parts of the coupling can make disconnection of the components possible.
